Task: Answer the multiple-choice question.
Question: Which drug exhibits a 4.428\% hERG inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any additional words.
Options:
a: CSC(=O)CC(=O)NC(=O)c1ccccc1
b: CCN(CC)c1ccc(-c2n[nH]c(=S)n2-c2ccccc2C)cc1
c: Cn1nc(C(=O)NCc2cccnc2)c2ccccc2c1=O
d: O=C(NCCCN1CCN(Cc2ccccc2)CC1)c1nnc(Cc2c(F)cccc2Cl)o1
Answer: c. Cn1nc(C(=O)NCc2cccnc2)c2ccccc2c1=O
