I thought when être was followed by a noun or pronoun the subject would be c’est, like c’est mon fils or c’est la mienne. Isn’t celui also a pronoun? Is it because il is also the subject of the verb manger?

In other words, doesn't "Il faut que je sois parti d'ici neuf heures" essentially mean "I'll have to be gone in nine hours"?

"It's quite difficult but useful."

Why can't you use 'plutot' in this sentence?

Is 'assez' used for quite while plutot for 'rather'?

A sentence mentions-

La compagnie pour laquelle je travaille a les meilleurs résultats du secteur.The company for which I work has the best results in the industry.

I would like to ask whether “dans laquelle” is also acceptable ?

Also if a sentence is given-

L’automne est la saison .................... les feuilles jaunissent. 

I came up with the following options-

pendant laquelle/ dans laquelle/ en laquelle 

Which of the above is grammatically accurate?

Je vous remercierais pour votre réponse.

 not necessarily overly friendly, would one still use the subjunctive?
