Task: Answer the multiple choice question.
Query: Which drug exhibits a -20.612% human ether-à-go-go related gene (hERG) inhibition at 10uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any additional words.
Options:
a) CCCCCCCC(=O)NNC(=O)c1ccc([N+](=O)[O-])cc1
b) O=C(OC(C(=O)NCC1CCCO1)c1ccccc1F)c1ccco1
c) CCOC(=O)C1=C(Cc2ccc(Cl)cc2)C(=O)c2ccccc2C1=O
d) O=C(O)/C=C/C(=O)N1CCN(C(c2ccccc2)c2ccccc2)CC1
Answer: a. CCCCCCCC(=O)NNC(=O)c1ccc([N+](=O)[O-])cc1
