B. 
Explanation:
Pronouns are the words used in the place of nouns to avoid repeating the word in a sentence. 
For instance, if I am talking about my friend "Lara", and telling about. 
   "Lara is a tall girl. Lara have a blonde hair. Lara loves reading books."
So, to avoid the repetition of the noun, we use pronouns like "she" or "her".
 Lara is a tall girl. She have a blonde hair. She loves reading books."
In the given sentence, the nouns are "Kwame" and "Enzo".
The correct pronoun to replace this is option B: Them.
<u>"Them"</u> is used to represent the group of people that have experienced the action described by the verb in the sentence. The action described in the sentence is "train". 
So, the correct option is B.
