Task: Answer the multiple-choice question.
Question: Which drug exhibits a -1.630\% 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 C/C(=N\O)C(C)(C)NC(=O)Nc1ccc(Cl)cc1
b CCN(CC)S(=O)(=O)c1ccc(C(=O)N2CCN=C2SCc2cccnc2)cc1
c Cc1csc(NC(=O)c2ccoc2C)n1
d CC(C)NC(=O)CN(c1cccc(Br)c1)S(C)(=O)=O
Answer: d. CC(C)NC(=O)CN(c1cccc(Br)c1)S(C)(=O)=O
