Task: Answer the multiple choice question.
Query: Which drug exhibits a -0.761\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any additional words.
Options:
(a) Cc1ccc(NC(=O)C(=O)NCCCN2CCCC2=O)cc1
(b) CSc1ccc(CCNC(=O)C2CCN(c3nnc(-n4cccc4)s3)CC2)cc1
(c) O=C(CCN=C1NS(=O)(=O)c2ccccc21)OCC(=O)c1ccccc1Cl
(d) COCCn1c(SCC(=O)Nc2cccc(NC(C)=O)c2)nc2c([nH]c3ccccc32)c1=O
Answer: c. O=C(CCN=C1NS(=O)(=O)c2ccccc21)OCC(=O)c1ccccc1Cl
