Task: Answer the multiple choice question.
Question: Which compound exhibits a -11.266\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, c, d, or e without using any other words.
Options:
a: C=CCN(c1ccc(C(=O)NCCN2CCOCC2)cc1)S(C)(=O)=O
b: Br.COc1ccc(-c2cn3ccccc3n2)cc1OC
c: CCCc1nc2c(o1)CC(CC(C)SCC)CC2=O
d: Cc1nn(CC(=O)Nc2ccc(Cl)cn2)c(C)c1Br
e: CCOc1ccc(CCNC(=O)CCc2nc3ccccc3[nH]2)cc1OCC
Answer: c. CCCc1nc2c(o1)CC(CC(C)SCC)CC2=O
