In the history of television technology, to whom is the credit usually given for inventing the first working television system?

Introduction / Context:
The invention of television was not a single event but the result of contributions from several inventors working on mechanical and electronic systems. However, many general knowledge books and competitive exam syllabi attribute the credit for inventing the first working television system to a specific pioneer. This question checks whether you are familiar with that widely accepted attribution and can distinguish it from the contributions of other important inventors in communication technology.

Given Data / Assumptions:

• The question asks about the inventor who is usually credited with the first working television system.
• The focus is on general knowledge usage rather than on detailed technical disputes.
• The options include Philo Farnsworth, John Logie Baird, Guglielmo Marconi and a generic None of the above.
• Only one of these names is commonly presented in basic GK sources as the inventor of television.

Concept / Approach:
John Logie Baird, a Scottish engineer, is widely recognised in school level general knowledge and many exam materials as the inventor of television. In the 1920s, he demonstrated a working mechanical television system that could transmit moving images over a distance. Although Philo Farnsworth later developed a fully electronic television system and made crucial contributions, the traditional answer for who invented TV in many simple GK questions remains John Logie Baird. Marconi is associated with wireless telegraphy and radio, not television. Therefore, in the context of such exams, Baird is the expected correct answer.

Step-by-Step Solution:
Step 1: Identify that the question is aimed at common GK understanding of the inventor of television.Step 2: Recall that many textbooks list John Logie Baird as the pioneer who first demonstrated television.Step 3: Compare the options and locate Baird among the choices as option B.Step 4: Recognise that Philo Farnsworth work is crucial for electronic television but is less commonly chosen in simple quiz style questions.Step 5: Exclude Marconi, whose main field was radio communication, and then select John Logie Baird as the answer.

Verification / Alternative check:
You can cross check by remembering that the earliest television demonstrations in Britain were associated with John Logie Baird, including live image transmission and early broadcasts. Standard general knowledge lists frequently pair his name directly with television. More advanced history of technology texts may discuss Farnsworth role in modern electronic television, but exam questions at basic level almost always expect Baird. Recognising the level of the exam helps confirm your choice.

Why Other Options Are Wrong:
Philo Farnsworth indeed played a key role in developing fully electronic television and is very important historically. However, the phrasing of many GK questions and the conventional school answer still credit Baird. Guglielmo Marconi is famous for wireless telegraphy and radio communication, not for television, so selecting him would mix up different communication technologies. The option None of the above is incorrect because one of the listed inventors, Baird, is accepted in the usual exam context.

Common Pitfalls:
Students may overthink the question if they have read more detailed histories of television that emphasise Philo Farnsworth contributions. Others may confuse radio and television inventors and pick Marconi. To avoid this, remember that many exam boards and textbooks provide a simple mapping: John Logie Baird for television, Marconi for radio, and Graham Bell for telephone. Keeping these standard pairings clear helps you answer quickly and accurately in competitive exams.

Final Answer:
In general knowledge questions, John Logie Baird is usually credited with inventing the first working television system.
