Identify the correct sentence.

a. Have you spoken to your professor about your grade in English class?
b. Have you spoken to your prof about your grade in english class?
c. Have you spoken to your Professor about your grade in English class?
d. Have you spoken to your Prof. about your grade in English class?

Yes, a.

Well, well, well, let me humorously analyze these options for you:

a. Have you spoken to your professor about your grade in English class?
- This option seems formal and straightforward.

b. Have you spoken to your prof about your grade in English class?
- Ah, a more casual and shortened version of professor. The prof is in the building!

c. Have you spoken to your Professor about your grade in English class?
- Now we're getting fancy with a capital P for Professor. The seriousness level is rising.

d. Have you spoken to your Prof. about your grade in English class?
- Ah, we're using an abbreviation here. Prof. is in the house!

So, my dear friend, all of these sentences are grammatically correct, but it depends on the level of formality you want to convey. Feel free to choose your preferred style!

The correct sentence is:

a. Have you spoken to your professor about your grade in English class?

To identify the correct sentence, we need to look for grammar and capitalization errors. Let's go through each option:

a. Have you spoken to your professor about your grade in English class?
This sentence is grammatically correct, and the word "professor" is properly capitalized. Therefore, option a is a possible correct answer.

b. Have you spoken to your prof about your grade in english class?
In this sentence, "prof" is not a standard abbreviation for "professor," and it is not capitalized. Additionally, "English" should be capitalized as it is referring to a specific class. Therefore, option b contains errors and is not the correct sentence.

c. Have you spoken to your Professor about your grade in English class?
This sentence is grammatically correct and properly capitalizes "Professor" and "English." Therefore, option c is a possible correct answer.

d. Have you spoken to your Prof. about your grade in English class?
In this sentence, "prof" is not a standard abbreviation for "professor," and it is not capitalized. Additionally, the abbreviation "Prof." should have a period after it. Therefore, option d contains errors and is not the correct sentence.

So, the correct sentence is either option a or option c. Both of them are grammatically correct and use the appropriate capitalization for "professor" and "English."
