The question doesn't make sense to me. What type of what?

a

The question doesn't make sense but if kelly20 means what i think he/she means then --electron seems a good answer.

But are kelly20 and mibn2cweus the same person? Why hasn't kelly20 listed the choices and why has the latter finished off the question?
