Problem statement: Answer the multiple choice question.
Query: Which drug exhibits a 11.807\% 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:

[b] COc1ccccc1CCNC(=O)CCn1c(=O)c2cccn2c2ccc(F)cc21
[c] COc1cccc(NC(=O)CC(=O)c2ccc([N+](=O)[O-])cc2)c1
[d] O=C(N=C1c2ccccc2CN1c1ccccc1)c1cccc([N+](=O)[O-])c1
Answer: b. COc1ccccc1CCNC(=O)CCn1c(=O)c2cccn2c2ccc(F)cc21
