Task: Answer the multiple choice question.
Query: Which compound exhibits a -0.020\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any other words.
Options:
a. Cc1cc(S(=O)(=O)NCCCN2CCOCC2)c(C)cc1Cl
b. CCCCNC(=O)CC1S/C(=N/N=C/c2ccc(OC)cc2)NC1=O
c. COc1ccc(S(=O)(=O)N/N=C\c2ccc([N+](=O)[O-])o2)c(OC)c1
Answer: a. Cc1cc(S(=O)(=O)NCCCN2CCOCC2)c(C)cc1Cl
