Problem statement: Answer the MCQ question.
Query: Which compound exhibits a -0.496\% 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: CC1=Nc2cc(C(=O)NCC3CCCO3)ccc2Sc2ccc(Br)cc21
b: O=C1c2ccc(-c3ccc4c(c3)C(=O)N(CCO)C4=O)cc2C(=O)N1CCO
c: O=C(O)CCN1C(=O)/C(=C/c2ccc(-c3nc4ccccc4s3)o2)SC1=S
d: CC(=O)Nc1ccccc1C(=O)C(=O)Nc1cccc(C(=O)NCc2ccc(C)cc2)c1
Answer: c. O=C(O)CCN1C(=O)/C(=C/c2ccc(-c3nc4ccccc4s3)o2)SC1=S
