your question didn't mention that interest rate 0.02 % per day / per week / per month / per 6 month / per annum.
well, I assume if interest rate is 0.02 % per annum . and we know, any Bank give us simple interest .
so, r = 0.02 % , T = 1 year , P = ?
SI = $ 9.99 ≈ $10
SI = P × R × T/100
$10 = P × 0.02 × 1/100
P = $ 50,000
so, we need to keep in this account ≥ P = $50,000
hence, option (A) is correct. according to my point of view
