Which of the following is an example of Arabian Sea drainage system ?

Question

Accepted Answer

Option 4, which includes the rivers Jojri, Bandi, and Jawai, is the correct answer as an example of the Arabian Sea drainage system. Here's why:

1. **Explanation for Option 4:**
   - **Jojri River:** This river is a tributary of the Luni River, which is one of the major rivers in the region that drains into the Arabian Sea. The Luni River flows through the arid regions of Rajasthan and Gujarat, eventually reaching the Rann of Kutch, which is connected to the Arabian Sea.
   - **Bandi River:** The Bandi River is another tributary of the Luni River. It contributes to the drainage system that ultimately leads to the Arabian Sea, reinforcing its inclusion in the Arabian Sea drainage system.
   - **Jawai River:** This river also feeds into the Luni River system. The Jawai Dam, built on this river, is a significant water source in the region, and its waters eventually contribute to the Arabian Sea drainage.

2. **Explanation for why other options are incorrect:**

- **Option 1 (Menal, Kothari, Berach):** These rivers are primarily part of the drainage system that flows into the Bay of Bengal. For instance, the Berach River is a tributary of the Banas River, which eventually joins the Chambal River, part of the Ganges Basin that drains into the Bay of Bengal.
   
   - **Option 2 (Jojri, Berach, Menal):** While Jojri is correctly part of the Arabian Sea drainage system, Berach and Menal are not. As mentioned, Berach is part of the Bay of Bengal drainage system, and Menal is not directly associated with the Arabian Sea drainage.
   
   - **Option 3 (Kothari, Som, Ruparel):** These rivers are also part of the Bay of Bengal drainage system. The Kothari River flows into the Banas River, and the Som River is a tributary of the Mahi River, which drains into the Gulf of Khambhat, part of the Arabian Sea, but the combination in this option does not accurately represent the Arabian Sea drainage system as effectively as Option 4.

In conclusion, Option 4 is the correct choice because it accurately represents rivers that are part of the Arabian Sea drainage system, specifically through their connection to the Luni River, which is a significant contributor to this drainage system.
