Correct answer: A
Key idea: Convert Shekhar’s rank from the last into rank from the top, then move Jigyasa seven places ahead.
In a class of 40, Shekhar is 16th from the last.
Shekhar’s rank from the top = 40 - 16 + 1 = 25th.
Jigyasa is seven ranks ahead of Shekhar, so her rank = 25 - 7 = 18th.
Answer: Option 0, “18th”, is correct.
