a) No it's not correct. Co-borrower must have a share in the property, then only she can avail the tax deduction benefit. Refer the following article in support of the opinion -

b) & c) Until and unless the department gets any clue from any other sources regarding these treatments which arises suspicion in their mind, nothing would happen. But if the jurisdictional AO or any other higher officer will have reason to believe about the same, then they might issue notice U/s 143 as well as U/s 148 for earlier years.
Department can gather information from the bank itself because at the time of taking loan the assessee must have submited the property documents in which it's clearly evident that the husband is only the owner.
