This question is clearly answered in the official IMM 7000 Guide: http://www.cic.gc.ca/english/information/applications/guides/EG7TOC.asp
From the list, select the type of dependant:
Type 1
The dependent is under the age of 19 and single (not married and not in a common-law relationship).
Type 2
The dependent is 19 years of age or older, has been financially dependent on a parent since before the age of 19 due to a physical or mental condition.
The following types of children are for applicants who started an immigration process before August 1st, 2014.
Type A
The dependant is under the age of 22 and single (not married and not in a common-law relationship).
Type B
The dependant has been continuously enrolled in and in attendance as a full‑time student at a post-secondary institution accredited by the relevant government authority and has depended substantially on the financial support of a parent either:
- since before the age of 22, or
- since marrying or entering into a common-law relationship (if it happened before the age of 22).
Type C
The dependant is 22 years of age or older, has depended substantially on the financial support of a parent since before the age of 22, and is unable to provide for himself or herself because of a medical condition.
Thus, it is obvious that in your case you should select "Type 1"
None. If you choose "Spouse" in question 10 then question 12 is automatically grayed out so that you can't type anything there. As it is not applicable for wife.
