Blood vessel pattern is capture because it is present in unique form for every person and will help in distinguishing a person from another person while scanning.
Other options are incorrect because light reflection or reaching near retina and light pattern are not the unique way for identification while scanning a person.Thus the correct option is option(D).

<h3>Central Processing Unit</h3>
The part of a computing device that cosnumes the most power is called the Central Processing Unit (CPU). This is due to the following reasons;
- The CPU consists of motherboard and battery that draws power from the socket.
- The Mother board is equipped with logic gates that are used to implement logic in the computer.
- The Logic gates are voltage signals that signify the binary information that are fed into the system.
