Task: Answer the multiple choice question.
Question: Which compound exhibits a -66.240% human ether-à-go-go related gene (hERG) inhibition at 10uM?
Constraint: You must select none, one or more options from a, b, c, d, or e without using any other words.
Options:
a: O=C(C1=C(O)C(=O)N(CCN2CCOCC2)C1c1ccccc1)c1cccs1
b: CCOC(=O)C1=NN(c2ccc(C)cc2)CC1C(=O)OC
c: Cl.O=C(CN1CCN(C2CCCCC2)CC1)Nc1ccccc1N1CCCCC1
d: O=C(c1ccc2c3c(cccc13)CC2)N1CCN(c2ncccn2)CC1
e: CCN1CCN(C(=O)CCc2nnc(CCc3ccccc3OC)o2)[C@@H](C)C1=O
Answer: c. Cl.O=C(CN1CCN(C2CCCCC2)CC1)Nc1ccccc1N1CCCCC1
