As the years passed and due to the advancement of the transistors the computers have become smaller in size.

Option (b) is true. With the advancement in the research in circuits used in the computer like Integrated Circuits the computers have become faster.
The response time of the operating system has reduced drastically.
Option (c) is wrong option. The computers have become cheaper. The transistors are cheaper compared to the vacuum tubes which are used in the earlier computers.
The price of the same computer (memory and time efficiency) has become less in the coming years than in the previous years with the advancement in the research of transistors.
Option (d) is true. Now-a-days computers support more and more number of applications. Computers has more number of applications in various and diversified fields.
