Task: Answer the multiple-choice question.
Query: Which drug exhibits a 12.566\% 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] O=C1CS/C(=C/C(=O)c2cccc(Cl)c2)N1
[b] CCOC(=O)CSc1nc(N)nc(C)c1Br
[c] Cc1cc(C)nc(N/N=C/c2ccco2)n1
[d] COCCNCC(=O)N1c2ccccc2Sc2ccccc21
Answer: a. O=C1CS/C(=C/C(=O)c2cccc(Cl)c2)N1
