Problem statement: Answer the multiple choice question.
Query: Which compound exhibits a 15.941\% 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 additional words.
Options:
a) CCOc1ccc(CC(=O)Nc2nccs2)cc1OCC
b) Cc1cccc(-n2c(O)c(C=NCCN3CCCCC3)c(=O)[nH]c2=O)c1
c) CCN1C(=C(C#N)C#N)C=Cc2ccccc21
d) O=c1c2[nH]c3ccc(F)cc3c2nc2n1CCCS2
Answer: c. CCN1C(=C(C#N)C#N)C=Cc2ccccc21
