Task: Answer the MCQ question.
Query: Which drug exhibits a 4.654\% 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: CCOC(=O)c1c[nH]c2c(C(=O)c3ccccc3)cc(Cl)cc2c1=O
b: CC(C)[C@H](NC(=O)c1ccc(F)cc1)C(=O)N(C)Cc1cccs1
c: C#CC(C)(CC)NC(=O)c1cc2nc(C3CC3)cc(C(F)(F)F)n2n1
d: Cl.Oc1cccnc1CCc1ccccc1
