For #1
the Int rate affects the price of a put or call differently depending on if the underlying is an equity or a bond

An increase in the risk free rate would cause
a Call Option on an Equity to Increase and a Call Option on a Bond to decrease in value
a Put Option on a bond to increase and a Put Option on a Bond to increase in value

The other two I do not know.

Reggie-
If you're just making sh*t up don't post, it doesn't help anyone - it's not funny to mess others up in the hopes that it may help you to pass. Not very ethical IMHO.
