Problem statement: Answer the multiple choice question.
Query: Which drug has a 6.621\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any additional words.
Options:
a: Cc1cccc(/C=N/NC(=O)CN2CCCCCCC2)c1
b: CCCNC(=O)c1cc(-c2ccc(OC)cc2)n(CCCOC)c1C
c: CCN(c1ccccc1)S(=O)(=O)c1ccc(N2CCN(c3ccccc3O)CC2)nc1
Answer: c. CCN(c1ccccc1)S(=O)(=O)c1ccc(N2CCN(c3ccccc3O)CC2)nc1
