Task: Answer the multiple choice question.
Query: Which drug exhibits a 2.221% hERG inhibition at a concentration of 10uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any additional words.
Options:
(a) O=C(/C=C/c1ccco1)NC(=S)Nc1cccc([N+](=O)[O-])c1
(b) Cc1ccc(NC(=O)COC(=O)CCn2c(C)csc2=O)c([N+](=O)[O-])c1
(c) Cc1ccc(/C=C(\C#N)C(=O)c2ccccc2)s1
(d) O=S(=O)(NC1CCCC1)c1ccccc1Cl
Answer: c. Cc1ccc(/C=C(\C#N)C(=O)c2ccccc2)s1
