Problem statement: Answer the multiple choice question.
Query: Which drug has a 1.919\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any other words.
Options:
a.) O=C(CSc1nc2ccccc2o1)N/N=C/c1ccccc1
b.) O=C(CCC(=O)N1CCSc2ccccc21)NCc1cccc(Cl)c1
c.) C=CCn1c(C(C)NC(=O)c2cccc(C)c2)n[nH]c1=S
Answer: a. O=C(CSc1nc2ccccc2o1)N/N=C/c1ccccc1
