Problem statement: Answer the multiple choice question.
Query: Which drug exhibits a 17.670\% 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) O=C(c1ccccc1)c1ccc(OCCO)cc1
(b) COC(=O)C1=C(CCc2ccccc2)NC(=O)NC1c1ccc(Cl)cc1
(c) Cc1ccc(-c2n[nH]c3c2C(c2ccccc2)N(c2ccc(C(=O)O)cc2)C3=O)cc1
Answer: a. O=C(c1ccccc1)c1ccc(OCCO)cc1
