Mumbai needs $1.4 \times 10^{12} \, L$ of water annually. Its effective surface area is $600 \, km^2$ and it receives an average rainfall of $2.4 \, m$ annually. If $10 \%$ of this rainwater is conserved,it will meet approximately:
- A$1 \%$ of Mumbai's water needs
- B$10 \%$ of Mumbai's water needs
- C$50 \%$ of Mumbai's water needs
- D$100 \%$ of Mumbai's water needs
