B1 and 3 only ✓ Correct

C2 and 5 only

D1, 2, 3 and 5 only

Correct answer: (B) 1 and 3 only

Explanation

Gender and caste are nominal variables, unordered categories, so statements 1 and 3 are correct.

Nominal variables classify cases into named groups with no inherent order.

Annoyance level is ordinal because its categories can be ranked by intensity.

Temperature in Kelvin is a ratio variable with a true zero.

Economic status is ordinal, running from lower to higher ranks.

Nominal data support only counts, modes and category-based statistics.
