Task: Answer the MCQ question.
Question: Which drug exhibits a 1.551\% 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.) Cc1ccc(NC(=O)CC2NCCNC2=O)cc1
b.) O=C(CCS(=O)(=O)c1ccccc1Cl)NCCC1=CCCCC1
c.) COc1ccc(/C(O)=C2/C(=O)C(=O)N(CC3CCCO3)C2c2ccc(O)c(OC)c2)cc1
Answer: b. O=C(CCS(=O)(=O)c1ccccc1Cl)NCCC1=CCCCC1
