Task: Answer the multiple choice question.
Query: Which drug has a 11.640\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any other words.
Options:
a. CC(c1ccccc1)N1CC(C(=O)O)CC1=O
b. COc1ccc(C2(O)CCN(CCCCOc3ccccc3)CC2)cc1
c. CC(C)CNC(=O)COC(=O)CNC(=O)c1cc(Cl)cc([N+](=O)[O-])c1
d. COc1ccc(C2C(C#N)=C(N)Oc3c2ccc2cccnc32)cc1OC
Answer: a. CC(c1ccccc1)N1CC(C(=O)O)CC1=O
