Option D is the answer because Digital Certificate is an entity that generates electronic and distributes them upon proving their identity sufficiently. In early days there was issues with people using the certificates that were not even issued by the organizations. Today it's a cryptographic technique which uses digital signatures and gives users a digital certificate that can be authenticated anytime online by any organization and is unique for every user having it.
Option A cannot be the answer because it has nothing to do with the identity of person but rather it is for specific fields.
Option B is not answer because it has no key and score matter to do with it.
Option C Web transactions has nothing to do with the certificates.
Answer:
The attached files contain the realization of a D flip-flop from an RS flip-flop. It also contains the truth tables for both kinds of flip-flops
Explanation:
An SR flip flop is like a light switch. Set turns it 'on' and reset turns it 'off'
A D type flip-flop is a clocked flip-flop which has two stable states. A D type flip-flop operates with a delay in input by one clock cycle.
D type flip-flops are easily constructed from an SR flip-flop by simply connecting an inverter between the S and the R inputs so that the input to the inverter is connected to the S input and the output of the inverter is connected to the R input.
