Consider the following rivers:1.Vamsadhara2.Indravati3.Pranahita4.PennarWhich of the above are tributaries of Godavari?

1. A

   1, 2 and 3

   (a) 1, 2 and 3. Indravati and Pranahita are Godavari tributaries, but Vamsadhara is an independent east-flowing river of Odisha–Andhra, not a Godavari tributary. Including 1 is wrong.

2. B

   2, 3 and 4

   (b) 2, 3 and 4. Pennar (Penna) is a separate Peninsular river to the Bay of Bengal, not a Godavari tributary. Including 4 fails.

3. C

   1, 2 and 4

   (c) 1, 2 and 4. Both Vamsadhara and Pennar are independent rivers. This set is wrong.

4. D

   2 and 3 only

   (d) 2 and 3 only. Indravati (from Chhattisgarh/Odisha) and Pranahita (Wainganga–Wardha system) join the Godavari. Vamsadhara and Pennar do not. That pair is the official key.

Summary. Official key is (d) 2 and 3 only. Indravati and Pranahita are major Godavari tributaries. Vamsadhara and Pennar are separate east-flowing rivers. Only 2 and 3 belong on the Godavari list.
