Identify the sentence that correctly uses the present tense.
a. my brother is attending nursing school right now.
b. my brother attends nursing school last year.
c. my brother has been a nursing student for the past two years.
d. my brother is a nursing student at the local community college.

d. my brother is a nursing student at the local community college.

Explanation:

The sentence that correctly uses the present tense is "D" because the speaker uses verb "to be" in the present simple tense in order to say something that happens in the present time. For the moment we know that "my brother" is actually a nursing student at the local community college.

Sentence A is in progressive tense because we have verb "to be + verb in -ING form" which indicates present continuous tense.

Sentence B is wrong because the modifier of time "last year" indicates past tense and the verb "attends" is being used in present tense.

Sentence C is in present perfect tense because we have the verb "have + verb to be in participle form" which indicates present perfect tense.
