Who is the director of the Sanskrit film \"Adi Sankara\", regarded as one of the earliest full length Sanskrit movies produced in India?

Introduction / Context:
Questions about landmark films often appear in the culture section of competitive exams. \"Adi Sankara\" is notable because it is widely recognised as one of the earliest full length Sanskrit feature films in India. Film and culture based MCQs frequently ask candidates to identify its director. The correct answer is G. V. Iyer, a director known for making films on philosophical and religious themes.

Given Data / Assumptions:

• The film mentioned is Adi Sankara.
• It is described as a Sanskrit film and an early example in that language.
• The options list R. V. Iyer, G. V. Iyer, Ransingh, and none of the above.
• We assume the exam refers to the director of this specific film, not producers or actors.

Concept / Approach:
The concept is matching a film title with its director. G. V. Iyer built a reputation for directing films based on Indian philosophy and classical themes, including works on Shankaracharya and other spiritual subjects. Adi Sankara is one of his well known films. By contrast, the other names are either distractors or not associated with this project. The approach is to recall the connection between G. V. Iyer and Sanskrit cinema.

Step-by-Step Solution:
Step 1: Read the film title Adi Sankara and remember that it is a Sanskrit language movie about the philosopher Shankaracharya. Step 2: Recall that G. V. Iyer is recognised for directing this film. Step 3: Check the options and identify G. V. Iyer among them. Step 4: Recognise that R. V. Iyer and Ransingh do not match the standard information you may have studied. Step 5: Note that none of the above is unnecessary because a correct specific name exists. Step 6: Choose G. V. Iyer as the correct answer.

Verification / Alternative check:
You can verify from film and culture notes stating that Adi Sankara was directed by G. V. Iyer and is regarded as the first or one of the first Sanskrit feature films in India. This association is repeated in multiple GK compilations, making it reliable. Remembering that G. V. Iyer specialised in philosophical themes can serve as an additional cue that he would be the director of a film on Shankaracharya.

Why Other Options Are Wrong:
R. V. Iyer and Ransingh are not recorded as directors of this film in standard references and are included only as distractors. None of the above is wrong because a correct director's name is provided in the list. Selecting any of these would conflict with widely accepted film history information and with the answer keys used in most culture oriented MCQs.

Common Pitfalls:
One pitfall is misreading the initials and confusing R. V. Iyer with G. V. Iyer, especially under exam stress. Another error is to avoid committing such details to memory because film based questions may seem less important. To prevent such mistakes, quickly note down a few landmark film facts, such as Adi Sankara directed by G. V. Iyer, and revise them before exams.

Final Answer:
The Sanskrit film Adi Sankara was directed by G. V. Iyer.
