Consider the position of Mohan

Mohan is 20th from the right and there are 17 students to the left of Mohan.

Therefore, the total number of persons in the line = 17 + 20 = 37 students

Dinesh's position from the left = Total number of persons in the line - Dinesh's position from the right + 1

⇒ Dinesh's position from the left = 37 - 15 + 1 = 23

Hence, the correct answer is "23rd".
