Task: Answer the MCQ question.
Question: Which drug exhibits a 16.043\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any additional words.
Options:
a) N#Cc1ccc(Cl)cc1NC(=O)CNCc1cccs1.O=C(O)C(=O)O
b) COC(=O)CCCCCN1C(=O)NC(c2ccccc2)C(C(=O)OCc2ccccc2)=C1C
c) Cc1ccc(S(=O)(=O)N(C)C)cc1NC(=O)CCNC(=O)c1ccco1
Answer: b. COC(=O)CCCCCN1C(=O)NC(c2ccccc2)C(C(=O)OCc2ccccc2)=C1C
