Who discovered the first practical method for freezing food that led to the development of the frozen food industry?

Introduction / Context:
This question addresses a major development in food technology: the invention of a practical method for freezing food so that it remains palatable and safe over long periods. The frozen food industry changed how people store and transport food. The key pioneer in this area was Clarence Birdseye, whose quick freezing method allowed vegetables, meat and fish to retain much of their original taste and texture. Recognising his name is a standard part of inventions related general knowledge.

Given Data / Assumptions:

• The subject is the first practical method for freezing food.
• The options include C. Birdseye, F. Rozenosh, G. Findus and R. Scott.
• The question asks which person is associated with discovering this method.
• Popular science and technology histories form the basis of the expected answer.

Concept / Approach:
Clarence Birdseye observed traditional freezing methods used by Inuit communities and later developed a quick freezing system using very low temperatures and rapid processing, which prevented large ice crystals from forming and damaging food structure. This innovation became the foundation for the commercial frozen food industry. The other names in the options do not match this contribution in standard exam references. Therefore, the correct answer is C. Birdseye, representing Clarence Birdseye.

Step-by-Step Solution:
Step 1: Recall that frozen food as we know it today became widespread in the twentieth century due to a quick freezing technique. Step 2: Associate the brand name Birdseye, often seen in frozen food products, with the inventor Clarence Birdseye. Step 3: Recognise that this inventor developed a process in which food is rapidly frozen at very low temperatures to preserve quality. Step 4: Compare this recollection with the options listed in the question. Step 5: Observe that C. Birdseye exactly matches the inventor's surname and initial. Step 6: Conclude that C. Birdseye is the correct answer and select it.

Verification / Alternative check:
To verify, one can recall that many frozen food packets in some countries bear the Birdseye brand name, honouring the inventor. Histories of food preservation frequently mention Birdseye as the person who made commercial quick freezing successful. The other names in the options are not commonly associated with this industry or discovery in well known sources, which confirms that Birdseye is the correct choice.

Why Other Options Are Wrong:
F. Rozenosh, G. Findus and R. Scott are not recognised widely as inventors of frozen food technology in basic general knowledge references. Some names may hint at food related brands, but the accepted historical credit for discovering the practical quick freezing method goes to Clarence Birdseye. Therefore, all these other options are distractors and do not correctly answer the question.

Common Pitfalls:
A common mistake is to treat all unfamiliar names as equally likely and guess randomly rather than linking the question to real world brand recognition and historical facts. Another pitfall is failing to associate technological advances in daily life, such as frozen vegetables and fish, with the people who invented them. Building simple mental connections between everyday products and their inventors can make such questions much easier to answer accurately.

Final Answer:
The person who discovered the first practical method of freezing food and helped create the frozen food industry is C. Birdseye, referring to Clarence Birdseye.
