OA - B
OG Verbal review states that for D, 'term' (singular) doesnt agree with 'have suggested' (plural).

But use of 'may' requires'have'.

The term ＂graphic　design＂suggests --> No subj verb agreement error
The term ＂graphic　design＂has suggested --> No subj verb agreement error

Can someone explain if there is subj verb agreement error in the below examples, more specifically in choice D above?

The term ＂graphic　design＂may suggest
The term ＂graphic　design＂may have suggested

Parallelism dude!
a la
Though it may have suggested you this, it has suggested me that.
So it's may have. May have is perfectly fine and also the second clause has "has". So it's D.

the use of "though" suggests the sentence needs a contrast of facts.

essentially, the meaning is "though X should suggest one thing, in reality X actually represents another".

The correct idiom out of all choices is B:
Though this... it has come to mean this...

vs D:
Though this may have... it has... (there is lack of contrast in the second part.

Stay away from using "have" whenever possible to use present tense. And, "have" is often used correctly when used as a verb for subject "people"

Avoid using "gerund" as verbs, often correct when used as a noun to describe preceding situation in preceding clause or to modify a clause after a comma.

@ GMATGuruNY,
Apart from whatever you've mentioned above as ERRORS in D, please let me know whether we can mention about the following aspect as a potential ERROR in Option D ?

The intended meaning of the original sentence is that the term ＂graphic　design＂ may suggest laying out corporate brochures and annual reports, BUT ＂graphic　design＂ DOESN'T suggest brochure and report layout itself. So the Option D seems to indicate that there is subtle change in meaning.

Correct me please if wrong!

P.S: In GENERAL, I think the following structure is GRAMMATICALLY correct -

Singular subject MIGHT HAVE or MAY HAVE. Right ?

This line of reasoning is sound.

Singular subject MIGHT HAVE or MAY HAVE. Right ?

The subject may be singular or plural.

The OE for SC97 in the OG12: The system might have founded a school.
Here, the subject for might have -- the system -- in singular.

SC119 in the OG12: Catastrophic impacts may have caused reversals.
Here, the subject for may have -- impacts -- is plural.
