Task: Answer the multiple-choice question.
Question: Which compound exhibits a 6.138% human ether-à-go-go related gene (hERG) inhibition at 10uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any additional words.
Options:
a Cc1[nH]c2c(Br)cccc2c1[C@H]1[C@@H](CC#N)C1(C)C
b COc1ccc(C2C(C#N)=C(N)Nc3onc(C(C)(C)C)c32)c(OC)c1
c COc1ccc(-c2cc(C(=O)OCC(=O)N(C(C)C)C(C)C)c3ccccc3n2)cc1
d CCC1=NN2C(=N)/C(=C\c3cccn3-c3ccc(C)c(C)c3)C(=O)N=C2S1
Answer: a. Cc1[nH]c2c(Br)cccc2c1[C@H]1[C@@H](CC#N)C1(C)C
