Explanation:

Time taken to travel = $\frac{\mathrm{Distance}}{\mathrm{Speed} \mathrm{of} \mathrm{available} \mathrm{mode} \mathrm{of} \mathrm{transport}}$

Considering the options, we have the travel times for (Mumbai – Kanyakumari, Bhubaneshwar – Chennai, Chennai – Kochi, Mumbai – Chennai) as,

$\frac{950}{40}$, $\frac{950}{30}$, $\frac{901}{30}$, $\frac{1000}{30}$

It can be observed that $\left(\frac{950}{40}\right)$ has the least value.

Hence, option (a).
