Problem statement: Answer the multiple choice question.
Query: Which drug has a 4.505\% 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) CCC(=O)N1CCc2cc(Br)cc(S(=O)(=O)CCC(=O)NCCc3ccccc3)c21
b) O=C(O)c1ccccc1C(=O)O
c) Cc1nc(-c2cccnc2)sc1C(=O)Nc1ccc(Cl)cc1
d) COc1ccc(C(C)=O)cc1CSCC(=O)O
Answer: b. O=C(O)c1ccccc1C(=O)O
