Conjugate the following "tú" command:

(tú, escribir) el proyecto.

escribe
escriba
escribas

The correct answer would be Escrinas

Since the tú form ends in -as after you remove the -ir from the stem word.

Escribir the remove the -ir

Now you are left with escrib

Then you add the -as since it is in the tú form

Hope this helps! :3
