Task: Answer the multiple choice question.
Question: Which drug exhibits a 0.987% hERG inhibition at a concentration of 10uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any other words.
Options:
a CCN1CCc2c(C#N)c(N3CCOCC3)nc(N3CCOCC3)c2C1
b Cc1cc(C)c(NC(=O)CSc2nc3ccc(NC(=O)CSc4nnnn4Cc4ccccc4)cc3s2)c(C)c1
c Cc1ccc(CNC(=O)C23CN(Cc4ccccc4)CC2C(c2ccc([N+](=O)[O-])cc2)=NO3)o1
d O=C(CCSc1ccccc1)N1CCN(C(=O)c2ccco2)CC1
Answer: b. Cc1cc(C)c(NC(=O)CSc2nc3ccc(NC(=O)CSc4nnnn4Cc4ccccc4)cc3s2)c(C)c1
