Task: Answer the multiple choice question.
Query: Which drug exhibits a 12.555% 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 additional words.
Options:
a: CCOCCCNC(=O)c1cc2c(=O)n3cccc(C)c3nc2s1
b: CCCOc1ccc(-c2nc(=S)[nH][nH]2)cc1
c: O=C(c1ccc(Oc2ccc([N+](=O)[O-])cc2Cl)cc1)N1CCCC1
d: COc1ccc(CCn2nnnc2C(CC(C)C)N2CCC(C(N)=O)CC2)cc1OC
Answer: a. CCOCCCNC(=O)c1cc2c(=O)n3cccc(C)c3nc2s1
