Task: Answer the multiple-choice question.
Question: Which drug has a 8.046\% 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=C(C1CC1)N1CCN=C1SCc1cccc(C(F)(F)F)c1
b N#Cc1nc(COc2ccc(F)cc2)oc1N1CCCC1
c CCOC(=O)C(C)(C)Oc1ccc(Cl)cc1
d CN(C)S(=O)(=O)c1ccc(NC(=O)c2cccnc2)cc1
Answer: c. CCOC(=O)C(C)(C)Oc1ccc(Cl)cc1
