If m and n are positive integers, and m=2n and k=7m, then -
Choose the correct option.
A) k is a factor of m/2. B) 2m is a factor of k. C) 3m is a factor of k/2. D) k is a factor of m. E) m/2 is a factor of k.
m=2n --&gt; m is even.   k=7m --&gt; m is factor of k, thus m/2 = integer must also be a factor of k.   Answer: m/2 is a factor of k..
