Task: Answer the multiple choice question.
Question: Which drug exhibits a 3.990\% 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(NC1CCCC1)C(c1ccsc1)N(Cc1ccccc1)C(=O)Cc1cccs1
[b] Cc1cc(C(=O)NNC(=O)/C=C/c2ccc(F)cc2)c(C)o1
[c] CN(CCC#N)C(=S)Nc1ccc(F)cc1
Answer: a. O=C(NC1CCCC1)C(c1ccsc1)N(Cc1ccccc1)C(=O)Cc1cccs1
