It helps to quote when you ask the question so that everyone else doesn't need to look up the rules or answer off the top of their head.

Tome of Magic
Sometimes books of forbidden lore are offered for sale in the markets and dark alleys of the settlements around Mordheim.
If a warband includes a wizard, he will gain an extra spell from the tome, permanently. He may randomly generate this new spell from his own list or the Lesser Magic list. See the Magic section for details. The benefits from each Tome of Magic apply to only one model.

Arcane Lore. Witch Hunters, Sisters of Sigmar and Warrior-Priests may not have this skill. Any warrior with this skill may learn Lesser Magic if he owns a Tome of Magic.
Option A if the model is a non-wizard as per your question.
Option C-ish (Lesser
Magic or spell from own spell list) if the model is a wizard and the Arcane Lore skill is not required.
Also note that the "benefits from each Tome of
Magic apply to only one model" so the Tome of
Magic cannot be given to another model to also learn spells after the first model has learnt one or more spells. Seems odd I agree and I remember Werekin saying as a joke in another thread that it is as if the first model is spoiling the pages after use.
@Von Kurst... I agree that it seems odd and inconsistent that for example a Beastmen Shaman can learn a single Lesser
Magic spell from a Tome of
Magic but a non-spellcaster with Arcane Lore can potentially learn all Lesser
Magic spells. The way that I would treat it is if the wizard wants to learn more than one Lesser
Magic spell (assuming that they learn other spells by default) then they would need to get the Arcane Lore spell like a non-wizard model.
