Choose the correct answer from the options given below

Options:

A-III, B-II, C-IV, D-I

A-IV, B-III, C-I, D-II

A-III, B-IV, C-II, D-I

A-III, B-IV, C-I, D-II

Correct Answer:

A-III, B-IV, C-II, D-I

Explanation:

B. HCF = Common terms are 2³3²and5 thus HCF = 2³×3²×5

D. HCF = Common terms are 2⁶and7⁴ thus HCF = 2⁶×7⁴

Thus, selecting the most appropriate option is (3).

The correct answer is option (3) : A-III, B-IV, C-II, D-I
