• A. A = Spiral, B = Annular, C = Reticulate, D = Scalariform, E.= Pitted with border, F = Pitted, simple
• B. A = Annular, B = Spiral, C = Scalariform, D = Reticulate, E = Pitted with border, F = Pitted, simple
• C. A = Annular, B = Spiral, C = Scalariform, D = Reticulate, E = Pitted, simple, F = Pitted with border.
• D. A = Spiral, B '= Annular, C = Scalariform, D = Reticulate, E = Pitted with border, F = Pitted, simple

Answer 1
