B) 217
C) 256
D) 320

Correct Answer:


B) 217

Description for Correct answer:
Here we have two sections A and B. Section A has 3 questions and B has 5 questions and one question from each section is compulsory according to the given condition.

Number of ways selecting one or more than one question from section A.

= \( 3 + 3 + 1 = 7 \)

Similarly, from section b = \( 1 + 5 + 24 + 1 = 31 \)

According to the rule of multiplication, the required number of ways in which a candidate can select the questions = 7 X 31 = 217
