hello !!
The cradle of a star is a cloud of hydrogen and dust .There are numerous such clouds in the universe .By the action of external forces - such as the explosion of a star - this cloud geta compressed and keeps pulling itself together due to increasing force of attraction among the particles. After a few hundreds of thousands of years , it begins to shine.A proto-star , a star in the early stages is formed .This keeps pulling
itself together while rotating and becomes hotter and hotter , till its interior reaches a temperature of around 10 million degree celsius. In the core of the star the fusion of hydrogen into helium releases an enormous amount of energy .Now the star becomes a main sequence star.It shines till it dies.
Hope this will help you.

The gas and dust are pulled together by gravity-B
They pulled together cloud collapses and becomes hot and dense-D
Heat and pressure cause nuclear fusion, which signals the birth star-E
