Question

Correct order, in decreasing trend, of reservoirs based on their capacity at full reservoir level (Mm\(^3\))

• A. Ukai $>$ Nagarjunasagar $>$ Sriramsagar $>$ Koyna $>$ Idukkii
• B. Nagarjunasagar $>$ Ukai $>$ Sriramsagar $>$ Idukki $>$ Koyna
• C. Nagarjunasagar $>$ Sriramsagar $>$ Ukai $>$ Koyna $>$ Idukki
• D. Nagarjunasagar $>$ Ukai $>$ Sriramsagar $>$ Koyna $>$ Idukki

Hint:

Nagarjunasagar is one of the largest reservoirs in India (over 11 BCM).
This helps place it first.
Idukki is a double-curvature arch dam located in a narrow gorge, which limits its storage volume compared to massive earthen/gravity dams, placing it last.
