The place located at the confluence of Alakananda and Pindar rivers is Kamaprayag (option 2).

To better understand, let`s look at each option individually:

1) Rudraprayag: This option is not the correct answer. Rudraprayag is actually the place where the Alaknanda and Mandakini rivers meet, not the Alakananda and Pindar rivers.

2) Kamaprayag: This is the correct answer. Kamaprayag is the place where the Alakananda and Pindar rivers merge. It is one of the five confluences (prayags) in the state of Uttarakhand, India.

3) Devaprayag: This option is not the correct answer for the given question. Devaprayag is the confluence of the Alaknanda and Bhagirathi rivers, which then form the Ganges River.

4) Vishnuprayag: Although this is a confluence of two rivers, it is not the confluence of the Alakananda and Pindar rivers. Vishnuprayag is the meeting point of the Alakananda and Dhauliganga rivers.

In conclusion, the correct answer is option 2,
