I am an 11-letter Indian city. Hints: 10, 2, 4 is a unit of length. The last 6…

Concept: In a letter-position coding puzzle, each hint decodes the letters standing at specific positions of the target word. The word that satisfies every hint simultaneously, directly in the order each hint gives, is the answer — a match on only some hints is not enough.

1. Number PONDICHERRY letter by letter: P-1, O-2, N-3, D-4, I-5, C-6, H-7, E-8, R-9, R-10, Y-11 — 11 letters, matching "an 11-letter city".

2. Positions 10, 2, 4 give R, O, D — ROD, a unit of length.

3. The last 6 letters (positions 6-11) are C, H, E, R, R, Y — CHERRY, a fruit.

4. Positions 9, 5, 3 give R, I, N — RIN, a well-known soap brand.

5. Positions 1, 8, 3 give P, E, N — PEN, used by a student.

6. Positions 7, 8, 3 give H, E, N — HEN, a bird.

7. Positions 6, 7, 5, 3 give C, H, I, N — CHIN, an organ on the face.

Cross-check: all six hints are satisfied directly, in the exact order each hint gives, by the same 11 letters of PONDICHERRY, with no contradiction. None of the other options have enough letters, or the correct spelling, to satisfy the clues referencing positions up to 9 and 10.
