Visitor visa for family while I study

[Sarzz2330]

Trying to complete documents for my study permit. Have a question regarding visitors visa for my family who will visit while I study.
1. In answering question in cic account, should it be (a) visitor visa - tourism or (b) visitor visa- all other types

2. The visitor visa application form speaks to funds, how much should it be? Since they will be visiting periodically

3. Also I am not there yet so what address do I put for them.

Thank you
