$\begingroup$ Note that the five tetromino shapes are commonly called L, I, T, S, O. The squiggly shape is S and the square is O. Looks like this puzzle is using a different coding, which then should be explicitly mentioned in the puzzle. $\endgroup$– BubblerCommented Jan 8, 2021 at 9:58

$\begingroup$ Aah, I was unsure of the "o" and "s". But after a quick google search i found "z" and just left the square to be a square, "s". $\endgroup$– Prim3numbahCommented Jan 8, 2021 at 10:12

Well...
Assuming that these are tetronimoes, the grid can be filled in like this:
using the knowledge that red is a square and grey is a line... the rest are pretty much forced.
Converting shapes back into their standard letters, we get L Z T S X T S T T around the central black square! Which is option B?
I should have noted:
While solving I wasn't able to keep the colours apart, so I assume that there is a reason for that in the title? (which I thought was Rotations and Reflections, but I may be incorrect).

$\begingroup$ No, you are correct, well done. $\endgroup$ Commented Jan 8, 2021 at 10:01

$\begingroup$ Where are you converting the shapes from? I can understand how given a set of shapes you could get those letters, but I'm unclear on which sequence of shapes you converted, and where you got them from. $\endgroup$– bobbleCommented Jan 8, 2021 at 15:32

2$\begingroup$ @bobble consider the 3x3 subgrid centered on the black square. Now, in the completed puzzle, consider what shape each cell in that 3x3 grid is a part of. This answer lists them in reading order (with X as the black square). $\endgroup$– hdsdvCommented Jan 8, 2021 at 18:51
