Task: Answer the multiple-choice question.
Query: Which drug exhibits a 14.303\% 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, or c without using any additional words.
Options:
(a) CCNC(=S)Nc1cc(-c2ccc(Cl)cc2)[nH]n1
(b) O=C1c2ccccc2-c2c1cccc2C(=O)N(CCO)CCO
(c) CCCC(=O)N(Cc1cc(=O)[nH]c2ccccc12)c1ccc(OC)cc1
Answer: a. CCNC(=S)Nc1cc(-c2ccc(Cl)cc2)[nH]n1
