(B) P4 + 3O2 ?N2 P4O6 (exclusively) (N2 is used to retard the further oxidation.)

Hello Student

Phosphorus trioxide (P4​O6​) is prepared by heating phosphorus in the limited supply of oxygen and nitrogen.

N2​prevents further oxidation of P4​O6​ to P4​O10​.

So option B is correct.

I hope this answer will help you.

Dear student,
Please find the attached answer to your question.

Phosphorus trioxide (P4​O6​) is prepared by heating phosphorus in the limited supply of oxygen and nitrogen. The nitrogen acts as a retarder and prevents the formation of P4O10
P4 + 3O2 + N2 → P4O6 + N2
(N2 acts as a retarder)
Hence option B) is correct.

Hope it helps.
Thanks and regards,
Kushagra
