Hey, good question!

Split NMR peaks are considered to be one signal. For example, the molecule in question 85 is expected to have 3 signals, at the protons in A), B) and D).

It's a bit of splitting hairs as far as language goes though (no pun intended).

I don't envision that they will ask you something like how many peaks a molecule has and the peak splitting will make the difference, usually when they ask how many signals a molecule has they are probing the idea of molecular symmetry, not splitting.

Please let me know if this is unclear!
