Task: Answer the multiple choice question.
Question: Which drug has a 19.335\% hERG inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any additional words.
Options:
a) O=C1NN=C(CSc2n[nH]c(=S)s2)CS1
b) COc1cccc(/C=C/C(=O)OCC(=O)NCC2CCCCC2)c1OC
c) CC(=O)NCCOc1nc(N2CCCCC2)nc(N2CCCCC2)n1
Answer: a. O=C1NN=C(CSc2n[nH]c(=S)s2)CS1
