Task: Answer the multiple-choice question.
Question: Which drug exhibits a -4.022\% 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: CCCOc1ccc(N2C(=O)C3ON(c4ccccc4)C(CCC)C3C2=O)cc1
b: CC(C)[C@H](NC(N)=O)C(=O)Nc1cccc([N+](=O)[O-])c1
c: CSCCC(N=Cc1c(O)n(-c2ccc(F)cc2)c(=O)[nH]c1=O)C(=O)OC(C)(C)C
d: Cc1nnc(-c2ccc(N3CCCCCC3)c([N+](=O)[O-])c2)o1
Answer: c. CSCCC(N=Cc1c(O)n(-c2ccc(F)cc2)c(=O)[nH]c1=O)C(=O)OC(C)(C)C
