if the sentenceis "ram kaam karwata hai"

that is akarmak kriya

that is sakarmak kriya bcoz there is answer for kya karwata hai

s

very true it is sakarmak kriya.

the question here is ;- raam kya karwaataa hai?

but in a sentence- bachcha pariksha bhavan mein beta hai.

you cannot ask - bachcha kya beta hai - right?

it is prernarthak kriya.

it is prernarthk kriya as he or she is not doing the work but getting done by another person

 it is prenarthak kriya

sakramak kriya

sakarnak kriya

It is a prernarthak kriya for sure
