Task: Answer the multiple choice question.
Query: Which drug has a 1.247% 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 O=C1CCN(Cc2ccc(Br)cc2)CCN1[C@H](CO)Cc1ccccc1
b Cc1nn(-c2ccc(Cl)cc2)c(Cl)c1/C=C(\C#N)C(N)=O
c CSc1ccc(C2NN=C(c3ccccc3)S2)cc1
d CCOC(=O)c1c(Nc2ccccc2OCCOC)n[nH]c1C
Answer: d. CCOC(=O)c1c(Nc2ccccc2OCCOC)n[nH]c1C
