Correct answer: D
Concept
When a row has N people, the left position of a person who is r-th from the right is N - r + 1. If two people occupy left positions p and q, the number strictly between them is |p - q| - 1 because both endpoint positions are excluded.
Application
Convert Daksh’s position to a position from the left: 63 - 17 + 1 = 47.
Raj is at position 20 from the left, so the difference between their positions is 47 - 20 = 27.
Exclude Raj and Daksh themselves: 27 - 1 = 26 people are between them.
Cross-check
Positions 21 through 46 lie strictly between positions 20 and 47. Their inclusive count is 46 - 21 + 1 = 26, confirming the result.
