Solution

The correct option is B molybdenum

Molybdenum is used as a target in Coolidge tube for product.

X- ray tube is an energy converter and it’s a device made of cathode and anode. An electrical current flows through the tube from cathode to anode, when electron undergoes a energy loss, which results in generation of x -rays.

Anode is a component in which x-rays are produced. It has 2 primary functions.

1.To convert electricity to x-ray

2.To dissipate heat in the process

For this, material such as molybdenum and tungsten are used with high atomic number which has good heat storage capacity and low rate of evaporation.
