Task: Answer the multiple choice question.
Question: Which drug exhibits a 22.328\% 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.) O=C(Nc1ccccc1N1CCOCC1)c1ccc2c(c1)OCO2
b.) CCOC(=O)C1=C(C)NC(=S)N(C=O)C1c1ccccc1
c.) O=C(CNc1cc(S(=O)(=O)N2CCOCC2)ccc1NCC1CCCO1)Nc1cccc(F)c1
Answer: b. CCOC(=O)C1=C(C)NC(=S)N(C=O)C1c1ccccc1
