Task: Answer the multiple-choice question.
Question: Which drug exhibits a 7.983% human ether-à-go-go related gene (hERG) inhibition at a concentration of 10uM?
Constraint: You must select none, one or more options from a, b, c, d, or e without using any additional words.
Options:
a: COC(=O)c1cc(C)nc(Sc2ccccc2NC(C)=O)n1
b: CCN1CCN(S(=O)(=O)c2c[nH]c(C(=O)OC)c2)CC1
c: COc1ccc(C(CC(=O)c2ccccc2)CC(=O)c2ccccc2)cc1OC
d: O=Cc1cn(-c2ccccc2)nc1-c1ccccn1
e: CC12CC(NC(=O)N1c1ccc(C(=O)N3CCN(c4ccc(F)cc4)CC3)cc1)c1ccccc1O2
Answer: b. CCN1CCN(S(=O)(=O)c2c[nH]c(C(=O)OC)c2)CC1
