Task: Answer the multiple-choice question.
Question: Which drug exhibits a 26.341\% 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 additional words.
Options:
a. COC(=O)Cn1c(C)nc(=O)c(-c2ccccc2)c1C
b. CC(C)(C)S(=O)(=O)c1cnc2c(-c3ccsc3)cnn2c1N
c. Cc1cc2c(cc1S(=O)(=O)N1CCN(c3ccccc3)CC1)OCC(=O)N2
d. CCCc1nn(C)c2c1C(c1ccncc1)C(C#N)=C(N)O2
e. COc1ccc(-c2c(C)nn3c(-c4ccccc4)cc(C)nc23)cc1
Answer: d. CCCc1nn(C)c2c1C(c1ccncc1)C(C#N)=C(N)O2
