Problem statement: Answer the multiple choice question.
Query: Which drug exhibits a 13.464\% 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 CN1CCN(CCCCOc2ccccc2C=O)CC1.O=C(O)C(=O)O
b CC1=NN(C(N)=S)C(=O)C1N=Nc1cc(Cl)ccc1Cl
c N/C(=N\OC(=O)c1cccc(Cn2cc(C(F)(F)F)ccc2=O)c1)c1ccccc1
d C=CCOc1ccc(C(c2c(O)nc(SC)[nH]c2=O)c2c(O)nc(SC)[nH]c2=O)cc1
Answer: d. C=CCOc1ccc(C(c2c(O)nc(SC)[nH]c2=O)c2c(O)nc(SC)[nH]c2=O)cc1
