Question no 40 with full explaination

Answer 1

It should be B) where the Rough Endoplasmic Reticulum is shown labeled as Q, we know it is involved in protein synthesis.
Now we also know that an eukaryotic cell undertakes a post translation modification (PTM) of the proteins that are synthesized. Some of these proteins will be active inside the cytoplasm others need to be secreted outside the cell, that feat is achieved by P that is Golgi apparatus for instance Glycosylation is a PTM occuring in Golgi,
so as per the above mentioned grounds option B is correct.
Hope this helps.
