Problem statement: Answer the multiple choice question.
Query: Which drug has a 1.934% hERG inhibition at a concentration of 10uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any other words.
Options:
a O=C(NS(=O)(=O)c1ccc(Cl)cc1)c1ccccc1
b Cc1ccc(S(=O)(=O)NC2(C(F)(F)F)NC(=O)N(CCc3ccccc3)C2=O)cc1
c Cc1ccc2nc(C)cc(N/N=C/c3cccc(O)c3)c2c1
d CCC1(c2ccccc2)C(=O)NCNC1=O
Answer: d. CCC1(c2ccccc2)C(=O)NCNC1=O
