Problem statement: Answer the multiple choice question.
Query: Which drug exhibits a 7.271\% human ether-à-go-go related gene (hERG) inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, c, d, or e without using any other words.
Options:
a: O=C(c1cc(-c2ccncc2)nc2ccccc12)N1CCN(c2ccccc2O)CC1
b: O=C(CCCc1c[nH]c2ccccc12)NCc1ccccc1F
c: O=C(N/N=C1/CCS(=O)(=O)c2ccc(F)cc21)c1ccccn1
d: Nc1ccccc1Nc1cc(-c2ccccc2)nn1-c1ccccc1
e: O=C(O)COc1ccc(Br)cc1C(c1c(C(=O)O)[nH]c2ccccc12)c1c(C(=O)O)[nH]c2ccccc12
Answer: b. O=C(CCCc1c[nH]c2ccccc12)NCc1ccccc1F
