Task: Answer the multiple choice question.
Question: Which drug exhibits a -3.553% hERG inhibition at a concentration of 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(CCCn1cnc([N+](=O)[O-])n1)Nc1cc(Cl)ccc1O
b: CCOC(=O)c1ccc(-c2n[nH]c(=O)c3ccccc23)cc1
c: Cc1nn(C)cc1CN(C)C(=O)CCc1nnc(CCC2CCCCC2)o1
d: COc1cc(C(=S)N2CCOCC2)ccc1OC(=O)/C=C/c1ccco1
Answer: b. CCOC(=O)c1ccc(-c2n[nH]c(=O)c3ccccc23)cc1
