The simple present tense serves to express a GENERAL TRUTH: something that is true now and is expected to be true ALWAYS.
B: the prevailing price...prompts allegations
Here, the usage of prompts (simple present tense) implies that the price ALWAYS PROMPTS allegations -- not the intended meaning.
Eliminate B.

The past perfect tense (had + VERBed) serves to express an action completed before another past event.
C and D: the prevailing price...had risen
Here, had risen (past perfect) implies that the price completed rising before another past event, but no other past event is offered.
Thus, the usage of the past perfect is unwarranted.
Eliminate C and D.

To raise means TO LIFT SOMETHING.
E: the prevailing price...raised from 27 cents
Here, it is unclear what the price lifted.
Eliminate E.

The correct answer is A.

COMMA + VERBing serves to express an action that happens at the same time as or as a result of the main action.
OA: The prevailing price rose from 27 cents to 31 cents overnight, prompting allegations that noodle shop owners had colluded to fix their prices.
Conveyed meaning.
When the price ROSE overnight, it also -- as a result of this action -- was PROMPTING allegations that noodle shop owners had colluded to fix their prices.
