Kanji reading help

[xrac00]

本冊 is not a kanji compound (not in dictionary), so would it be read as "honsatsu", "honsaku", or "motofumi"(kunyomi)? Why?

 

[undrentide]

Any context?

初級１本冊 sorry, that's all there is

 

[Toritoribe]

That's ほんさつ. It's not so common word; probably a back-formation word of the antonym 別冊[べっさつ] "separate volume".
