Problem statement: Answer the multiple choice question.
Question: Which drug exhibits a 2.496\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, c, d, or e without using any other words.
Options:
[a] O=C(CCNC(=O)c1ccccc1)N/N=C/c1ccc([N+](=O)[O-])cc1
[b] Cc1ncc(CN2CCCC(C(=O)Nc3ccc(-c4cccc(F)c4)cc3)C2)s1
[c] N#CC(C#N)=Cc1ccc(N2CCOCC2)cc1
[d] COc1cc(CCCN2C(=O)C(=O)NC[C@@H]2c2ccccc2)cc(OC)c1OC
[e] O=C(O)c1cccc(N(CCO)CCO)c1
Answer: a. O=C(CCNC(=O)c1ccccc1)N/N=C/c1ccc([N+](=O)[O-])cc1
