Answer:
The third sentence is correct. (Even though I think 'Rita' is written incorrectly)
Correct sentence: "Rlta received an A on her math test, a B on her blology
test, and an A- on her history test."
Step-by-step explanation:
I think that the 3rd sentence is correct because the word 'received' is spelled correctly and in the other sentences it is spelled incorrectly. Though in the 3rd sentence, Rita is spelled incorrectly. It was spelled 'RIta' instead of Rita but that may simply be a typo or since it's a name, it might just be spelt like that.
