Hi, guys. I hope you all well.
I need a help about circuit analysis.(mesh analysis)
In the circuit schematic which will given below, which mesh option is true ?

If I'm not mistaken, technically both would work if you keep track of your voltages and currents properly, though one is probably easier than the other (keeping in mind to properly use the right currents!). The second one you have I've seen referred to as a "superloop" before, though I'm not sure if that's the actual technical term. Point is: either one works, as they're both complete loops.

Sir, do you mean both circuits work if values are correctly choosen ?

You are correct: either should get you the same values, ultimately, if you are careful.

Try solving with both and see if you get the same answers.

Hi,

There are theories on this related to a 'sufficient' set of equations for a given circuit topology. I'd have to look them up for mesh because i dont use Mesh Analysis it is not as general as Nodal Analysis although it may reduce the number of equations by 1.
The theory on this concerns the branches traversed and/or nodes touched and/or 'trees' but i dont remember much about it because i dont use that type of analysis anymore. You could look it up on the web though. Try something like, "what constitutes a sufficient set of circuit equations" and maybe with "mesh analysis".
If you do find something interesting please do post it here.
