Task: Answer the multiple-choice question.
Query: Which drug exhibits a 4.695\% 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, or d without using any other words.
Options:
a) CC1(C)CC(NC(=O)C2CCN(S(=O)(=O)c3ccccc3C(F)(F)F)CC2)CC(C)(C)N1
b) O=c1[nH]c(SCc2ccccc2)nc2c1cnn2-c1ccc(F)cc1
c) O=C(NCCCO)c1ccc2[nH]c3ccccc3c2c1
d) Cc1ccccc1-n1c(O)c(C(c2ccncc2)c2c(O)n(-c3ccccc3C)c(=O)[nH]c2=O)c(=O)[nH]c1=O
Answer: b. O=c1[nH]c(SCc2ccccc2)nc2c1cnn2-c1ccc(F)cc1
