Task: Answer the multiple-choice question.
Query: Which compound exhibits a 3.345\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, d, or e without using any other words.
Options:
a. Cc1ccc(-c2csc3nc[nH]c(=O)c23)cc1C
b. CC1=CC(c2ccccc2)=Nc2ccc(C)cc2N1
c. CCc1ccc2oc(C(=O)Nc3nonc3C)c(C)c2c1
d. Cc1ccc2nc(N/C(N)=N/S(=O)(=O)c3ccc([N+](=O)[O-])cc3)nc(C)c2c1
e. O=C(CSc1nnc(C2COc3ccccc3O2)o1)Nc1ccc(F)cc1Cl
Answer: c. CCc1ccc2oc(C(=O)Nc3nonc3C)c(C)c2c1
