Task: Answer the multiple-choice question.
Question: Which compound exhibits a 24.484% human ether-à-go-go related gene (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) CCn1c(NC(C)=O)c(-c2ccccc2Cl)c(=O)c2ccccc21
(b) Cc1cccc(Oc2nccc(C(F)(F)F)c2C(=O)Nc2ccc(F)cc2F)c1
(c) CC(C)(C)OC(=O)CC[C@@H](C(=O)N1CCN(C(=O)OC(C)(C)C)CC1)n1cc(C(CO)NC(=O)OC(C)(C)C)nn1
(d) COc1ccccc1OCC(=O)Nc1nc(C)c(C)s1
Answer: a. CCn1c(NC(C)=O)c(-c2ccccc2Cl)c(=O)c2ccccc21
