Option: D
Explanation :A computer derives its basic strength from speed, reliability, accuracy, storage, versatility, consistency, communication, recalling, control sequence and cost reductions.

I. Speed:-

Computer processes data at a very high speed. It is much faster than human beings. A computer can perform billions of calculations in a second. Computer speed is measured in Mega Hertz (MHz) or Giga Hertz (GHz).

II. Reliability:-

Computer is very reliable because in modern computer electronic components rarely break or fail.

III. Accuracy:-

Accuracy means that the computer provides results without any errors. Computer can process large amounts of data and produce results accurately. Computer result can be wrong only if the data given is not correct.

IV. Storage/Memory:-

Computer can store a large amount of data permanently or temporarily. People can use permanently stored data at any time. For example a computer can store thousands of books easily.

V. Versatility:-

Computer is a versatile machine so it can perform different types of tasks. That is why it is being used in every field of life. Computer is used in hospital, bank, office, and at home etc.

VI. Consistency:-

Computer works in a consistent way. It does not lose concentration due to heavy work. In other words, computer does not become tired or bored.

VII. Communication:-

Computer have capability to communicate with other computers. Therefore, these computers can share data, instructions, and information.

VIII Recalling:-

A computer can recall the stored data and information as and when required. In addition, computer can recall the required data in a few seconds.

IX Cost Reduction:-

Computer can perform a difficult task in less time and less cost.
In short, a computer derives its basic strength from speed, reliability, accuracy, storage, versatility, consistency, communication, recalling, control sequence and cost reductions.

Option: B
Explanation :The IR which stands for the instruction register contains the last instruction fetched.
The instruction register (IR) or current instruction register (CIR) is the part of a CPU’s control unit that holds the instruction currently being executed or decoded.
An instruction register holds a machine instruction that is currently being executed. In general, a register sits at the top of the memory hierarchy. A variety of registers serve different functions in a central processing unit (CPU) – the function of the instruction register is to hold that currently queued instruction for use.
All the others options are registers which are used for the fetch operation.
