Problem statement: Answer the multiple-choice question.
Query: Which drug exhibits a 9.861\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any other words.
Options:
[a] O=C(N/N=C/c1ccccn1)c1ccc2nc[nH]c2c1
[b] Cc1ccc(SCCC(=O)Nc2ccccc2Br)cc1
[c] Cc1cc(=O)[nH]c(N/N=C/CCc2ccccc2)n1
Answer: a. O=C(N/N=C/c1ccccn1)c1ccc2nc[nH]c2c1
