Reference case property for checkbox question

Hi! I have one form with a checkbox question (list of vegetables - this
question is saved as a case property). A follow-up form contains a set of
questions for each vegetable selected. Since the value of the checkbox
question has multiple values, I’m not sure how to reference the individual
vegetable in each question.

Ex:

Form 1 - Select seeds you want:
Tomatoes
Cucumbers
Carrots

Form 2 - (if the user selected tomatoes in Form 1, then display the
following question)
Did the tomatoes grow?
