Correct option is B

Correct Answer: (B) 30
Given:
From P to Q, the driver knows 5 routes.
From Q to R, the driver knows 3 routes.
From R to S, the driver knows 2 routes.
Logic:
To find the total number of routes from P to S, we multiply the number of routes for each segment of the journey.
So, the total number of routes from P to S is:
5×3×2=305 \times 3 \times 2 = 30
