Within how many days minimum subscription should be received?

The correct answer is A. 60.

The minimum subscription period for a new customer is 60 days. This means that if you sign up for a subscription today, you will be billed for 60 days of service. You can cancel your subscription at any time, but you will still be billed for the full 60 days.

Option B is incorrect because it is more than the minimum subscription period. Option C is incorrect because it is less than the minimum subscription period. Option D is incorrect because it is not a valid option.
