Task: Answer the multiple choice question.
Query: Which drug exhibits a 2.567\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any other words.
Options:
a: CCOC(=O)C1CCCN(C(=O)c2cc3c(-c4cccc(OC)c4)nn(C)c3s2)C1
b: CCc1ccc(N2CCN(C(=O)c3ccc(OC)c(OC)c3)CC2)cc1
c: COc1cc2c(cc1O)CC[n+]1cc3c(OC)c(OC)ccc3cc1-2
d: CN(C)S(=O)(=O)N1CCC(c2ccc(F)cc2)C(COc2ccc3c(c2)OCO3)C1
Answer: a. CCOC(=O)C1CCCN(C(=O)c2cc3c(-c4cccc(OC)c4)nn(C)c3s2)C1
