• B. (C) is an example of non-statistical data, whereas (A), (B), and (D) are examples of statistical data.
• C. All are examples of statistical data.
• D. Only (C) is an example of statistical data.

Answer 1

The correct option is B (C) is an example of non-statistical data, whereas (A), (B), and (D) are examples of statistical data.

The answers to the questions which require the proper collection of data along with its presentation and respective analysis, falls under the category of statistical data.

While the answers which involve only single valued number or term, forms the part of non-statistical data.

Now, consider the given examples, here in (A), (B), and (D) proper collection of data is required to answer each of these questions.
Hence, these three form the part of statistical data.

Whereas, the answer to example (C) is single-valued, i.e., $7$ and does not require any data collection.
Thus, (C) falls under the category of non-statistical data.
