A) 0.1404
B) 0.1755
C) 0.3159
D) 0.0189

In 30 seconds, a bat can consume an average of 5 mosquitoes. To find the probability that a bat consumes four mosquitoes in this time interval, we can use a Poisson distribution with λ = 5.

P(X = 4) = (e^-5)(5^4)/(4!) = 0.1755

Therefore, the answer is choice B.
