Task: Answer the multiple-choice question.
Question: Which compound exhibits a 10.267\% 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: S=c1[nH]nc(COc2ccccc2)n1/N=C/c1cccc(Br)c1
b: COC(=O)CN1C(=O)COc2ccc(S(=O)(=O)NCc3ccccc3)cc21
c: COc1cccc(S(=O)(=O)NCc2ccc(C(=O)Nc3ccc(C)cc3)cc2)c1
d: CCc1cccc(NC(=S)N(CCOC)C2CCN(C(C)=O)CC2)c1
Answer: a. S=c1[nH]nc(COc2ccccc2)n1/N=C/c1cccc(Br)c1
