A group is singular hence eliminate B,D.

Eliminate C for change of meaning - testing will only be done on something that has been built or being built, also unless it is built we dont know how much electricity it uses.
in A and E , looking at the end of sentence we'll notice E correctly compares electricity used by the new chip to that used by current computer chips.

E is correct.

In one of the subject verb questions I've solved way before, there was a sentence which said "a variety of "plural noun" are" as the right answer. Does anybody remember? How come "are" is used instead of "is"? Thats what had confused me and made me select choices with plural verbs.. Please help.

Case A:

When the SANAM pronouns (some, any, none, all, more/most) or quantity words (half, 10%, 3/4th, quarter etc.) are used, the verb takes up the number (singular /plural) of the accompanying noun:

Plural:
Some of the slices ARE eaten.
Majority of the students ARE lazy.
Half of the bags ARE blue.
10% of the books ARE damaged by fire.

Singular:
Some of the pizza IS eaten.
Majority of the student-union IS upset.
Half of the sky IS blue.
10% of the library IS damaged by fire.

Case B:

The above concept however does not apply for collective nouns (group, team, class, bevy, pool, etc.) A collective noun is always singular. Therefore,

A group of students HAS been selected......... (the correct option of the subject sentence)
A bevy of girls IS approaching from right.

In the example you gave, "variety of 'plural noun' ARE", the word 'variety' was probably considered a quantity word and therefor the verb took up the number ( singular/plural) of the accompanying noun (Case A above).

This is a subject verb agreement problem again. The subject here is "group"... "of students" is just a description of the group. Whenever you see an "of", just check if it is meant to confuse the subject. Thus to agree with singular subject "group", must be a singular verb "has".

eliminate (B) and (D) for the use of "have" instead of "has".

Now start reading A, C and E in parallel.

"has been selected" is correct in all three. Then (A) says "for testing". It should be "for testing of" or simply "to test". Thus accept C and E and reject A.

C - "notepad to be built on"..."which are also power stingy".
E - "notepad being built around" ... "green, power stingy".

E is more crisp and C is unnecessarily wordy. "which are also" is not required when comma separated characteristics can be mentioned.

Thus E is the correct option.
