Correct — A, 4, 3, 1 and 2. The Yamuna's main right-bank tributaries rise on the Malwa Plateau / Bundelkhand and join it in sequence from west to east: Chambal (4) is the westernmost, joining near Etawah; then Sindh (3); then Betwa (1), joining at Hamirpur; and Ken (2) is the easternmost, joining near Chilla (Banda). So west-to-east reads Chambal, Sindh, Betwa, Ken = 4, 3, 1, 2, which is option (a).

Why the other options are wrong — (b) Betwa, Ken, Sindh, Chambal — this neither runs west-to-east nor east-to-west correctly; Chambal (westernmost) cannot be last.  (c) Sindh, Ken, Betwa, Chambal — jumbled; Ken is the easternmost and cannot come second, and Chambal cannot be last.  (d) Ken, Sindh, Betwa, Chambal — this is essentially east-to-west (reversed) and misplaces Ken at the start.

Concept: The Yamuna is the largest tributary of the Ganga, meeting it at Prayagraj (Triveni Sangam). Along its middle course it collects several right-bank tributaries draining the Vindhyan uplands and Bundelkhand — Chambal, Sindh, Betwa and Ken. Their confluences lie progressively eastward: Chambal (westernmost) → Sindh → Betwa → Ken (easternmost).
