In a binomial distribution `B(n , p=1/4)` , if the probability of at least one success is greater than or equal to `9/(10)` , then n is greater than (1) `1/((log)_(10)^4-(log)_(10)^3)` (2) `1/((log)_(10)^4+(log)_(10)^3)` (3) `9/((log)_(10)^4-(log)_(10)^3)` (4) `4/((log)_(10)^4-(log)_(10)^3)`

A

`frac(1)(log_10 4+log_10 3)`

B

`frac(9)(log_10 4-log_10 3)`

C

`frac(4)(log_10 4-log_10 3)`

D
