Task: Answer the multiple choice question.
Query: Which drug has a -3.359\% 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 additional words.
Options:
a: COCC(=O)Nc1cccc2ccccc12
b: COC(=O)c1cn(-c2ccccc2)nc1-c1ccc(OC)cc1
c: O=C(Cn1ncc2c1-c1ccccc1OC2)N(Cc1ccco1)C1CCCCC1
d: CCN(CC)CCOc1cc2c(nn1)Oc1ccccc1N2C.Cl.O
Answer: d. CCN(CC)CCOc1cc2c(nn1)Oc1ccccc1N2C.Cl.O
