Problem statement: Answer the multiple-choice question.
Query: Which drug exhibits a 16.894\% 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 COC(=O)N/N=C/c1ccc(Oc2ccccc2)cc1
b O=C(Cc1cccs1)N(c1ccc(F)cc1)C1(C(=O)NC2CCCCC2)CCCC1
c CN(C)C(/C=C/Nc1cccc(Br)c1)=C(C#N)C#N
d Nc1nonc1-n1nnc(C(=O)N/N=C/c2cc(Br)ccc2O)c1CNc1ccccc1
Answer: c. CN(C)C(/C=C/Nc1cccc(Br)c1)=C(C#N)C#N
