The correct answer is "Selling Treasury Bills and Treasury Bonds".
The other options are not possible because: <u>collecting taxes </u>is not "borrowing" <u>Issuing stock </u>- this is something that companies do when they sell a share in the ownership of it, not government And goverments don't usually <u>borrow from banks, </u>instead they issue documents promissing to bay back the money (along with an interest) to whoever buys those documents: selling Treasury Bills and bonds.
