Correct option is B)

Rajeev's watch gains 1 minute in an hour.So, it will gain 24 minutes per day.

Sanjeev's watch loses 2 minutes in an hour.

So, it will lose 48 minutes per day.

After 10 days Rajeev's watch gains 240 minutes i.e. 4 hours. and Sanjeev's watch loses 480 minutes i.e. 8 hours.

Hence, after 10 days their watches show the same time 4 hour.

Thus the correct answer is 10 days.
