From 1) m={5,7,11,13,17,19,23,25,29} - m is divisible by itself ,or itself and 5(Prime), So 1 Should not be sufficient

From 2) m = {3,7,9,11,13,17,19,21,23,27,29} - m is divisible by itsefl ,or itself and 3(Prime), so 2 is not sufficient.

from 1& 2 m= {5,7,11,13,17,19,23,29} - So only m is divisible by itself.

Astonishingly, the OE is not C.

{5,7,11,13,17,19,23,25,29} all numbers divisible only by 1 prime
Check it: all primes divisible only by itself, and 5 and 25 divisible only by one prime - 5
A it is.

another explanation is that when the number is odd and not divisible by 3, the next prime numbers are 5 and 7; the first number divisible by both 7 and 5 is 35, but 35 is out of definition, so it has to be only one distinct prime factor, thats why A is correct

if it is not divisible by 5, then 3 and 7 are possible and it could be for example 21 with two distinct primes
