Task: Answer the multiple choice question.
Question: Which drug exhibits a 11.973\% human ether-à-go-go related gene (hERG) inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any other words.
Options:
a. CCc1ccc(NC(=O)[C@H](C)NC(=O)C2CCN(C(=O)[C@@H](N)CC(C)C)CC2)cc1.Cl
b. CCOC(=O)c1c(C)c(C(=O)N2CCCCCC2)c(C)n1CC
c. O=C(C/C=N/OCc1ccc(Cl)cc1Cl)c1ccc(Cl)cc1
d. Cc1cc(-c2ccccc2)n2ncc(-c3ccccc3)c2n1
Answer: a. CCc1ccc(NC(=O)[C@H](C)NC(=O)C2CCN(C(=O)[C@@H](N)CC(C)C)CC2)cc1.Cl
