Select the most appropriate option to fill in the blank No. 3.
Show answer & explanation
Correct answer: C
Explanation
The correct answer is option 3, i.e., mosquito.
Blank 3 Word Type: Noun (subject acting as giving disease)
Explanation: The sentence says "If a mosquito capable of spreading yellow fever bites an infected monkey, the ___ can then give the disease to humans."
The correct noun is the one that refers back to the mosquito (the one doing the biting and transmitting).
Mosquito is correct because it is the one spreading the disease.
Monkey is the source of infection, not the transmitter to humans.
Human and animal don't logically fit here.
Correct Sentence: ...the mosquito can then give the disease to humans.
Conclusion: The correct option is mosquito.
