Task: Answer the multiple choice question.
Question: Which drug exhibits a 15.959\% human ether-à-go-go related gene (hERG) inhibition at 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(CSc1c[nH]c2ccccc12)NCC1CCCO1
b: O=C(CCn1nnc2ccccc21)N1CCC(O)(c2cccc(F)c2)CC1
c: O=C(Nc1ccc(F)cc1F)c1cccn(Cc2ccccc2)c1=O
d: Cl.O=C1CC2(CCCC2)CC(=O)N1CCCCN1CCN(c2ncccn2)CC1
e: Cc1ccn2cc(-c3cccc(NC(=O)CCC(=O)O)c3)nc2c1
Answer: a. O=C(CSc1c[nH]c2ccccc12)NCC1CCCO1
