Problem statement: Answer the multiple choice question.
Question: Which drug has a 18.100\% 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 other words.
Options:
a: CCc1nnc(NS(=O)(=O)c2ccc(NC(=O)c3cccc4ccccc34)cc2)s1
b: Cc1ccn(CC(=O)N2N=C(C(F)F)CC2(O)C(F)F)n1
c: CCOC(=O)c1ccccc1NC(=O)CN(c1ccccc1OC)S(C)(=O)=O
d: COC(=O)C(CC(=O)c1ccc(Cl)cc1)c1ccc(C(C)C)cc1
Answer: b. Cc1ccn(CC(=O)N2N=C(C(F)F)CC2(O)C(F)F)n1
