Task: Answer the multiple-choice question.
Query: Which drug has a -1.999\% 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] C=CCSc1nnc(NC(=O)CCN2C(=O)C3CC=CCC3C2=O)s1
[b] O=C(O)C1=NN(c2ccccc2)C(=O)CC1
[c] FC(F)(F)c1ccc(/C=N/NC(=S)NC2CCCCC2)cc1
[d] COc1cnn(Cc2ccccc2)c(=O)c1SCc1ccccc1
Answer: d. COc1cnn(Cc2ccccc2)c(=O)c1SCc1ccccc1
