Show answer & explanation

Correct answer: A

Explanation

The correct answer is option 1 i.e. allows.
Context: The sentence is describing a present and ongoing fact — the increase in greenhouse gases makes the Earth’s atmosphere trap more heat. So, the verb should be in present tense singular form.
Meaning of the words:
Allows: present tense, singular verb, means gives permission or makes possible.
Allowed: past tense, means gave permission or made possible earlier.
Allow: base form, not suitable here because the subject “increase” is singular.
Allowing: present participle form, not correct in this context.
Correct word: Allows
Reason: The subject is “The increase in greenhouse gases,” which is singular. Therefore, the correct verb is “allows.”
Final Sentence: The increase in greenhouse gases, particularly carbon dioxide, allows the Earth’s atmosphere to trap more heat.
Hence, the chosen option is correct.
