Task: Answer the multiple choice question.
Question: Which drug has a 1.239% human ether-à-go-go related gene (hERG) inhibition at a concentration of 10uM?
Constraint: You must select none, one or more options from a, b, or c without using any other words.
Options:
[a] O=S(=O)(C=C(c1ccccc1)c1ccccc1)c1ccccc1
[b] O=C(Cn1cnc2ccccc2c1=O)NCC(=O)N1CCN(c2ccccn2)CC1
[c] C=CCN=C(NC#N)SCCc1ccccc1
Answer: c. C=CCN=C(NC#N)SCCc1ccccc1
