He bought a t-shirt and a cap.
Interjunction
This is due to it being a statement
Ludere means to trick. Collusion is secret, illusion is a trick, elude is to avoid escape. These are not options. A prelude is an introduction - almost like a taste to trick you into reading, hearing, seeing more. An ablution is a washing - not connected to a trick at all. Ablution is your answer.
Internal conflict, I think. I am sorry if it's wrong!
