Task: Answer the multiple-choice question.
Query: Which drug has a -0.109\% 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 other words.
Options:
a: O=C(COc1ccccc1)NCC(=O)Nc1cccc2ccccc12
b: CCOC(=O)CCC(NC(=O)CCCC(=O)NC(CCC(=O)OCC)C(=O)OCC)C(=O)OCC
c: O=C(CCn1c(=S)[nH]c2ccccc2c1=O)NCCCN1CCOCC1
d: O=C(O)c1nc(NCc2ccccc2)ncc1Cl
Answer: c. O=C(CCn1c(=S)[nH]c2ccccc2c1=O)NCCCN1CCOCC1
