Task: Answer the multiple-choice question.
Question: Which drug exhibits a -0.660% human ether-à-go-go related gene (hERG) inhibition at a concentration of 10uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any other words.
Options:
a) CN1C(=O)C2C(c3ccc(N(C)C)cc3)NN(Cc3ccccc3)C2C1=O
b) COCCN(C(=O)c1ccco1)C(C(=O)NC1CCCC1)c1cccs1
c) CCN1CCn2c1nc(N1CCCCC1)nc2=O
d) O=C(NCCCN1CCOCC1)C1CC(=O)N(C2CCCCC2)C1
Answer: c. CCN1CCn2c1nc(N1CCCCC1)nc2=O
