Task: Answer the multiple choice question.
Query: Which compound exhibits a 20.462\% hERG inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any other words.
Options:
a: Cc1cccc(N(CC(O)CN2CCCC2)S(=O)(=O)c2ccccc2)c1
b: CCOC(=O)C1=NOC(CNC(=O)c2c(-c3ccccc3Cl)noc2C)C1
c: O=C(Nc1ccc(N2CCCC2)c(Cl)c1)c1cccs1
d: CCOC(=O)C(NCCOC)(NC(C)=O)C(F)(F)F
Answer: c. O=C(Nc1ccc(N2CCCC2)c(Cl)c1)c1cccs1
