Problem statement: Answer the MCQ question.
Question: Which drug exhibits a 1.027\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any other words.
Options:
a. CCOC(=O)C1CCCN(C(=O)c2cc3cc(F)ccc3[nH]2)C1
b. COc1ccc(/C=C/C(=O)CC(O)(c2ccccc2)C(F)(F)F)cc1
c. CC(C)C(=O)N1CCN(c2ccc(NC(=O)c3ccc(Br)o3)cc2)CC1
d. CCOC(=O)C1=C(CSc2nc(C)cc(C)c2C#N)OC(N)=C(C#N)C1c1cccs1
Answer: d. CCOC(=O)C1=C(CSc2nc(C)cc(C)c2C#N)OC(N)=C(C#N)C1c1cccs1
