Which of the following rivers were part of Harappan Civilization's geographical area :

(A) Indus
(B) Ravi
(C) Krishna
(D) Kaveri

Choose the correct answer from the options given below :

(A), (B) only

The correct answer is Option (1) → (A), (B) only

The Harappan Civilization, also known as the Indus Valley Civilization, developed in the northwestern region of the Indian subcontinent. It was centered around the Indus River and its major tributary, the Ravi River. These rivers played a vital role in the civilization's development as they provided a source of water for agriculture, transportation, and trade.

The other rivers mentioned, Krishna and Kaveri, are not associated with the Harappan Civilization's geographical area. The Krishna River is located in southern India, while the Kaveri River is even further to the south. The Harappan Civilization was concentrated in the northwestern part of the Indian subcontinent, in what is now modern-day Pakistan and northwest India.

So, the correct option is [1].
