Show answer & explanation
Correct answer: D
Explanation
The correct answer is option 4 i.e. that has.
Context: The sentence talks about the rise in global temperature that has already occurred.
Analysis of the given options:
- which had – past perfect; doesn't match with present implication
- that is – present tense mismatch with “already occurred”
- which have – plural verb; incorrect for singular subject 'rise'
- that has – correct tense and subject-verb agreement
Correct word: that has
Reason: 'Rise' is singular, so we need 'has' (not 'have'), and the phrase 'already occurred' fits with present perfect.
Hence, the chosen option is correct.
