Explanation from Nazar:

Skeleton of the sentence:

A surge have raised hopes that there is a recovery finally underway.

The problems in the original sentence:

1. The subject of the sentence is "A surge", which is singular, and the verb "have" is in PLURAL. 

2. There is/ there are type structures are always seen as awkward and redundant in GMAT.

Eliminate A.

Other issues in the wrong options:

BEING:

Being is not always WRONG though it is wrong 95% of the time. We must know when the use of BEING is is wrong and when the use of BEING is correct.

BEING is CORRECT:

1. If it used as auxiliary verb in PASSIVE sentence of progressive TENSES.

Example:

Active: They were playing football.

Passive: Football was being played by them.

Active: We are writing explanations.

Passive: Explanations are being written by us.

2. If it is use as GERUND.

Example:

Being heavily committed to the work brings success. 

When the use of BEING is WRONG:

If the use of BEING is with Case in Apposition:

Example:

Mr. John, being the head of the department, has made the decision.

Revised: Mr. John, the head of the department, has made the decision.

--> See the revised option is good, and the use of being in the first option does not add anything in the sentence. 

If we see any BEING used with appositive, we can ignore the BEING. 

Now, see the BEING in the options

Past simple:

We use past simple tense in those sentence where there will have past marker such as yesterday, last night, last year, last decade, year in the past. We don't have any such past marker in the sentence.

Eliminate the option E.

Answer is D.
