Task: Answer the multiple choice question.
Question: Which drug exhibits a -18.582\% 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, d, or e without using any other words.
Options:
a. COc1ccc(/C=N/NC(=O)c2cc(C34CC5CC(CC(C5)C3)C4)[nH]n2)cc1O
b. COc1ccc(N2C(=S)N(C(=O)c3ccccc3)C(=Nc3ccccc3)C2=Nc2ccccc2)cc1
c. CCN(CC)CCN1C(=O)c2ccccc2NC1c1ccccc1F
d. O=C(OCC(=O)N1CCCC1=O)c1ccc(O)cc1O
e. Cc1cccc(CSC2=NCCN2C(=O)c2ccc(S(=O)(=O)N(C)C)cc2)c1
Answer: c. CCN(CC)CCN1C(=O)c2ccccc2NC1c1ccccc1F
