Task: Answer the multiple-choice question.
Question: Which drug exhibits a 4.533\% 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(NCC1OCCCN1S(=O)(=O)c1cc(F)ccc1F)C(=O)NC1CCCC1
b: COc1ccc(NC(C)C(=O)N/N=C/c2ccccc2OCc2cccc(Br)c2)cc1
c: C/C(N)=C(/C#N)C(=O)CSc1nc2cc(Cl)ccc2c(=O)n1-c1ccc(C)cc1
d: COc1ccc(C2SCC(=O)N2Nc2ncc(Cl)cc2Cl)cc1
e: N#Cc1ccccc1CSc1nc2ccsc2c(=O)n1Cc1ccccn1
Answer: a. O=C(NCC1OCCCN1S(=O)(=O)c1cc(F)ccc1F)C(=O)NC1CCCC1
