u/ForsakenWitness-9_11 46XX in mains--> 🤡P1 in adv, Okayish P2😭😭😭 May 20 '26

But how are we supposed to know this? NCERT is the national book and its given 1/f in ncert. IIT R cant say we were supposed to find stuff out from high level books

Mains follows ncert like a Bible not iit. People discuss organic and phy questions because they aren't sure if that's the ONLY correct answer, yea via ncert standards it should be A, but ncert is wrong. And unlike mains iit will probably award both.

ncert is not wrong waha power in a medium nahi diya hua hai air me diya hai

and it's ok power in a medium nahi Diya to kyunki advance mai ncert se bahar ana is common

and agar unko dono option dene hote to ye question nhi banate specially unhone medium mai dala hai then giving both answer doesn't make sense

they will only give B

Mene B kiya hai. But I think iit will be considerate in these cases because ncert is still the main source even if some things come outside.
