Task: Answer the multiple choice question.
Query: Which compound has a 19.640\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any additional words.
Options:
a CC1(C)CC(=O)C=C(c2cccc(CO)c2)C1
b O=C(NCN1CCOCC1)c1cnccn1
c O=C(O)Cn1cc(/C=C2/SC(=O)N(CC(=O)N3CCCCCC3)C2=O)c2ccccc21
Answer: a. CC1(C)CC(=O)C=C(c2cccc(CO)c2)C1
