Task: Answer the multiple choice question.
Question: Which compound has a 10.283\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any other words.
Options:
(a) O=c1cc(CN2CCOCC2)c2cc(Cl)c(O)cc2o1
(b) O=C(COc1cccc2ccccc12)N/N=C/c1ccncc1
(c) CN(c1cccc(NS(=O)(=O)c2ccccc2)c1)S(C)(=O)=O
(d) CCOc1ccccc1Nc1nc(N)nc(CSc2nccc(C)n2)n1
Answer: a. O=c1cc(CN2CCOCC2)c2cc(Cl)c(O)cc2o1
