Task: Answer the multiple choice question.
Question: Which compound exhibits a 19.574\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any additional words.
Options:
a: CCC(NS(=O)(=O)c1cccs1)c1ccc(C)cc1
b: CCN1C(=O)c2ccc(C(=O)Nc3ccc(O)cc3C)cc2C1=O
c: COCc1nnc(NC(=O)c2ccc(S(=O)(=O)N(C)c3ccccc3)cc2)o1
d: CN1CCC(C2Oc3ccccc3Sc3ccc(Cl)cc32)CC1.O=C(O)/C=C\C(=O)O
Answer: b. CCN1C(=O)c2ccc(C(=O)Nc3ccc(O)cc3C)cc2C1=O
