Task: Answer the multiple choice question.
Question: Which drug exhibits a 8.518\% 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) CN1CCN(c2ccc(CNC(=O)c3cc4ccccc4o3)cc2)CC1
b) O=C(CNC(=O)c1ccc([N+](=O)[O-])cc1)N/N=C/c1c[nH]c2ccccc12
c) COc1cc(-c2[nH]nc3c2C(c2ccoc2)C(C#N)=C(N)O3)cc(OC)c1OC
d) Cc1cccc(NC(=O)Nc2ccc(C)c(C)c2)n1
Answer: d. Cc1cccc(NC(=O)Nc2ccc(C)c(C)c2)n1
