Problem statement: Answer the multiple choice question.
Query: Which drug has a 18.720\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a or b without using any additional words.
Options:
a O=C(CSc1ccc(-c2ccco2)nn1)N1CCCCC1
b O=C(N/N=C/c1ccccc1OC(F)F)c1cc(-c2ccncc2)nc2ccccc12
Answer: b. O=C(N/N=C/c1ccccc1OC(F)F)c1cc(-c2ccncc2)nc2ccccc12
