The answer is A. It is the only answer that shows the "now" money being doubled with the added $2

Because Ryan starts with a deposit of $50, it narrows the choices to A, C, or D

Next the question states that he deposits an amount that doubles his savings, so that narrows it down to to A

The question also states that the bank gives him $2 for maintaing a savings pattern, so that could be C or A

The answer is A because it includes all the necessary parts of the statment: dtarting at 50, times 2, and + 2
