Task: Answer the multiple choice question.
Question: Which drug exhibits a 12.340\% 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 other words.
Options:
(a) CCOC(=O)N1CC=C2C(C#N)=C(N)C(C#N)(C#N)[C@H](c3ccccc3OCC)[C@H]2C1
(b) CCOC(=O)c1sc(=S)n(C)c1N
(c) COc1ccc(-c2nc(-c3ccccc3)c(-c3cc([N+](=O)[O-])ccc3C)[nH]2)cc1OC
(d) COc1ccccc1C1(O)CCN(CC(=O)Nc2c(C)nn(C)c2C)CC1
Answer: d. COc1ccccc1C1(O)CCN(CC(=O)Nc2c(C)nn(C)c2C)CC1
