• A. $10$
• B. $7$
• C. $32$
• D. $64$

Answer 1

The correct option is C $32$

There are 5 stages: Question 1, question 2, question 3, question 4, and question 5.
There are 2 choices for each question (Yes or No).
So the total number of possible ways to answer is:
$2\times 2\times 2\times 2\times 2=32.$
