Task: Answer the multiple choice question.
Query: Which compound exhibits a 3.104% 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 other words.
Options:
a Br.O=c1cc2c(n[nH]1)CCCC2
b Cc1cccc(CS(=O)(=O)Cc2ccc(C(=O)NC3CCCCC3)o2)c1
c C=C1N2CCC(CC2)C1(O)c1ccc(C)cc1.Cl
d Cc1occc1-c1nnc(SCC(=O)N2CCN(c3ccc(F)cc3)CC2)n1C
Answer: a. Br.O=c1cc2c(n[nH]1)CCCC2
