Answer:
B. Surpass
Step-by-step explanation:
In the context, the word "eclipse" is used to show that a certain organism has far more sensory receptors in their noses than humans do. So, look for an answer choice that means something similar to "much more".
A. "Underestimate" is irrelevant because it is the opposite.
C. "Maximum" doesn't indicate "much more"; it simply means that there's a high limit.
D. "Sustain" does not refer to "much more"; it's more about the endurance.
Thus, B (surpass) is correct answer.
Hope this helps!
