Task: Answer the multiple choice question.
Query: Which drug exhibits a 21.266\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any other words.
Options:
(a) CCNC(=S)Nc1ccc(OCc2nc3ccccc3s2)cc1
(b) Cc1csc(NC(=O)Cc2ccc(Cl)cc2)n1
(c) O=C(Cn1cnc2c(cnn2-c2ccc(Cl)cc2)c1=O)NC1CCCCC1
Answer: c. O=C(Cn1cnc2c(cnn2-c2ccc(Cl)cc2)c1=O)NC1CCCCC1
