Task: Answer the multiple choice question.
Query: Which compound exhibits a 12.068\% 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 other words.
Options:
(a) COCCN(CCOC)S(=O)(=O)c1ccc(NC(=O)c2cnccn2)cc1
(b) O=C(CCc1nnc(-c2ccc3c(c2)OCO3)o1)NCCc1ccccc1F
(c) O=C1C=C(N(CCO)CCO)C2(CCCCC2)O1
(d) Cc1ccc(C(=O)N/N=C/c2ccc(OC(=O)c3ccccc3Cl)cc2)cn1
Answer: a. COCCN(CCOC)S(=O)(=O)c1ccc(NC(=O)c2cnccn2)cc1
