First I thought it is C but then I changed my mind because I saw *which makes*
Makes is singular. Right?
Can someone please explain about makes? I am lost.
Thanks!

Hi sparkles3144,
This SC begins with a list of items, but uses the word 'AND', so we're supposed to treat this as a plural subject.
We'll need a plural verb and a plural noun to match.
1) Verb - between 'is' and 'are', we'll need to use 'are.' Eliminate A and E.
2) Noun - between 'component' and 'components', we'll need to use 'components.' Eliminate B.
3) Style - we're told that the four listed items make up 55% of the volume of blood, so they are NOT the only components. The word 'main' is required. Eliminate D.
Final Answer: C
GMAT assassins aren't born, they're made,

In addition to what Rich said, "makes" is indeed singular. It should be singular since it refers only to "plasma", which is also singular.
