What option should you change the mask to in order for the text to be visible?

To make the text visible, the mask option should be set to "None." This choice effectively disables any masking effect applied to the text layer, allowing it to be fully visible as it reveals all of the layer’s content without any restriction.

Using a mask typically involves concealing parts of a layer based on the shape of the mask. By selecting "None," you ensure that the text is displayed in its entirety, without any clips or cut-outs.

Other options like "Cut Out," "Invert," or "Reveal All" alter the mask's behavior in ways that could obscure the text, either by masking out areas or changing which portions of the layer remain visible. "Cut Out" would hide parts of the text according to the mask shape, while "Invert" would reverse the mask, potentially hiding the text instead of showing it. "Reveal All," while seemingly similar to "None," may still leave the masking effects intact in certain situations. Therefore, "None" is the best option for ensuring complete visibility of the text.
