Task: Answer the multiple choice question.
Question: Which drug exhibits a -19.622\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any other words.
Options:
(a) COc1cccc(C(=O)Nc2nnc(SCC(=O)NC3CC3)s2)c1
(b) Cc1cccc(OCC(=O)NC(C)C(=O)N/N=C/c2c(OCc3ccccc3)ccc3ccccc23)c1
(c) C=CCn1c(O)c(C(CC)=NCCc2ccccc2)c(=O)[nH]c1=O
Answer: c. C=CCn1c(O)c(C(CC)=NCCc2ccccc2)c(=O)[nH]c1=O
