Question

why are you doing study ​

Answer 1

Answer:

The simple present implies an activity pursued over a long timespan: it would typically be used to ask someone what curriculum or topic of study they are engaged in when they are studying

Answer 2

"Why are you doing the study?" is an interrogation sentence of the present continuous tense.

• The tenses are divided into three parts: present tense, past tense and future tense.
• The present tense is divided into four kinds: Present indefinite, present continuous, present perfect and present perfect continuous tense.
• Present continuous is identified when something is continuously being done. Like in this case, studying is being done.
• Here, the question is being asked using the question the word 'Why'.

So, it is an interrogation sentence where studying is a continuous process.
