Task: Answer the multiple-choice question.
Query: Which drug exhibits a 4.306\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, d, or e without using any other words.
Options:
a: Br.N=C(N)SCc1nc2ccccn2c1Br
b: COc1ccccc1N(C)S(=O)(=O)c1ccc(C(=O)OCC(=O)N2CCCCCC2)cc1
c: COc1ccccc1C(CC(N)=O)c1ccco1
d: CC(C)n1c(SCC(=O)N2CCCC2)nc2c1c(=O)n(C)c(=O)n2C
e: COc1ccc2nc(C(F)(F)Cl)c(C#N)c(N)c2c1
Answer: d. CC(C)n1c(SCC(=O)N2CCCC2)nc2c1c(=O)n(C)c(=O)n2C
