In answer choice A, the subject of the first part of the sentence is "paper". "Of all kinds" describes the word "paper". You can think of it like this:

Because paper (of all kinds) is the biggest single component …

We have a singular subject (paper) and a singular verb (is). The subject and verb agree in number.

In E, the subject of the first part of the sentence is "kinds". "Of paper" describes the word "kinds":

All kinds (of paper) is the biggest single component …

We have a plural subject (kinds) and a singular verb (is). The subject and the verb do NOT agree in number. We can eliminate E.
