Bootcamp Ochem question

I completely understand that A is the most stable conformation because the bigger isopropyl group is on the equatorial position, while the smaller methyl group is on the axial group.

So my question is:
From what I recalled, Wedge means "up", and Dash means "down". Since the question contained both wedges, I though the cyclohexane chair formation needs to have both the isopropyl group and the methyl group pointing "up" (option C) even though it is not as stable, and if you want the most stable conformation, I thought it'd look like this- see attached

Wedge does not mean up, it means coming out of the page (towards you). Dash means going into the page (away from you). The wedged lines for these two substituents means that they are cis or both pointing in the same direction (either both up or both down in this case). Just by knowing this, you can eliminate the answers down to A and C. As you know C is less stabilizing so A would be your answer.

Wedge is up.

but if you flip it,

the up will be down,


and in this case the answer is the flipped version.

Look again

Its a cheeky question, but @DatRav27 is on the money.

And isopropyl has to be equatorial .
