Task: Answer the multiple-choice question.
Question: Which drug has a 1.404\% hERG inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any other words.
Options:
[a] O=C1c2ccccc2NC(c2ccc(-c3cccs3)o2)N1O
[b] Cc1cc(C)nc(-n2ncc3c2CC(c2ccc(F)cc2)CC3=O)n1
[c] CSC1=NC2(C)CCCCC2C12C=CC(=O)C=C2
[d] O=C(CNC(=O)c1ccc2ccccc2c1)NCc1ccc(F)cc1
Answer: a. O=C1c2ccccc2NC(c2ccc(-c3cccs3)o2)N1O
