Can some explain why the OE is not C for this.
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.

Though the answer is uniform value, m is different. i am not how properly designed the question.
