Task: Answer the multiple choice question.
Query: Which compound exhibits a 21.007% 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 O=C(NC1(C(F)(F)F)C(=O)Nc2c1c(=O)[nH]c(=O)n2Cc1ccccc1)c1ccc(Cl)cc1Cl
b COc1ccc(-c2cc(C(=O)Nc3c(C)nn(Cc4ccccc4Cl)c3C)no2)cc1OC
c CC(Oc1cc(F)ccc1[N+](=O)[O-])C(=O)Nc1ccc(S(=O)(=O)N2CCCC2)cc1
d COCCCN1C(=O)/C(=C/c2ccc(CNS(=O)(=O)c3ccccc3)o2)C(C(=O)OC)=C1C
Answer: a. O=C(NC1(C(F)(F)F)C(=O)Nc2c1c(=O)[nH]c(=O)n2Cc1ccccc1)c1ccc(Cl)cc1Cl
