Correct answer: A
Explanation
The correct answer is option 1 i.e. help.
Context: The subject is puzzles, activities, and mazes, which is plural.
Meaning of the words:
Help: assist (present tense, plural)
Helped: assisted (past tense)
Helps: assists (present tense, singular)
Had helped: past perfect tense
Correct word: help
Reason: We need the correct verb form to match the plural subject. Plural subjects take the base form without ‘s’: they help.
Hence, the chosen option is correct.
