Graham Stanley · Answer 1

none of the above options are true.

Explanation:

option with M at the end are exluded beacuse M is message and it cannot be send openly so option a, d, e, f, g cannot be options

the option b and c includes with Alice private key Apr which alice cannot send to any individual so these options are also excluded
