Problem statement: Answer the multiple choice question.
Question: Which drug exhibits a 6.421\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any additional words.
Options:
a: Cc1cccc(/C=N/NC(=O)c2ccc(Br)cc2)c1
b: COC(=O)C1C(O)=C(C=NC2CCCCC2)C(=O)CC1(C)C
c: CCC1COCCS(=O)(=O)N1Cc1ccc(F)cc1
Answer: b. COC(=O)C1C(O)=C(C=NC2CCCCC2)C(=O)CC1(C)C
