Task: Answer the multiple-choice question.
Query: Which drug has a 3.414\% 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 additional words.
Options:
a) Cc1nc(N2CCC(C)CC2)c2oc3ccccc3c2n1
b) O=C(Cc1ccccc1)Nc1ccccc1N1CCN(c2ccccc2)CC1
c) CN(C)CCCNC(=O)Cc1ccc(Br)cc1
d) CCOC(=O)/C(C#N)=N/Nc1cc(OC)ccc1OC
Answer: d. CCOC(=O)/C(C#N)=N/Nc1cc(OC)ccc1OC
