Task: Answer the multiple choice question.
Query: Which compound exhibits a 5.075\% 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 additional words.
Options:
(a) O=C(N/N=C/c1cccnc1)c1cc(-c2ccccc2Cl)nc2ccccc12
(b) Cc1ccccc1NC(=O)CSc1nnc(NC(=O)c2ccco2)s1
(c) COc1ccc2cc(C(N)=O)/c(=N/NC(=O)c3ccco3)oc2c1
(d) O=C(/C=C/c1ccccc1)OCC(=O)N1CCN(c2ccccc2)CC1
Answer: a. O=C(N/N=C/c1cccnc1)c1cc(-c2ccccc2Cl)nc2ccccc12
