Task: Answer the multiple choice question.
Question: Which drug has a 19.855\% 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 additional words.
Options:
a. O=S(=O)(NC(=NCc1ccccc1)c1ccc(F)cc1)c1ccc(Cl)cc1
b. Cc1ccc(NC(=O)CC(C)N2CCCC2)cc1
c. Cc1ccc(NC(=O)c2cncc(Br)c2)c(O)c1
d. CCN(CC(=O)Nc1c(F)cccc1F)C(=O)CCCc1nc2ccccc2c(=O)[nH]1
Answer: a. O=S(=O)(NC(=NCc1ccccc1)c1ccc(F)cc1)c1ccc(Cl)cc1
