Wait.....What do you mean?
Answer:
values have been declared but not initialized nor allocated memory. So you are not allowed to use "values.length"
Assuming the data was encrypted with YOUR public key, you'll need YOUR private key to decrypt it. That's answer e.
a and b are not solutions by themselves, of course you need to use the decryption algorithm, but a key goes with it.
c would be about symmetric encryption, but this is asymmetric, so different keys are used for encryption and decryption
d is possible, but it would mean anyone can decrypt it (after all the key is public), so then there's no point in encrypting it in the first place.
So e is the only logical answer.
If you are on a desktop computer you can press the top row key "F3" and a little box will pop up and you can type the word you are looking for in there and it will find that word on the page you are on and take you straight to it.
