Task: Answer the multiple choice question.
Question: Which drug has a 4.638\% 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. CCOC(=O)c1sc(NC(=O)CSC(=S)N2CCOCC2)nc1C
b. CCOC(=O)C1CN(S(C)(=O)=O)c2cc(CC(=O)OC)ccc2O1
c. COC(=O)CCN(c1ccccc1)S(=O)(=O)c1cc(-c2cc(C)no2)ccc1OC
d. O=C1C2CCCN2C(c2cccc(Br)c2)N1c1ccc(F)cc1
Answer: b. CCOC(=O)C1CN(S(C)(=O)=O)c2cc(CC(=O)OC)ccc2O1
