If you make a color or swatch in InDesign, the only Color Mode options will be CMYK, RGB, or Lab. It sounds like your instructor wants you to limit the color and swatch use to CMYK, with the CMY values set to 0.

I think that just means to not use any colors other than black, and even though tints of black or levels of black that aren't 100% don't look like what we normally think of as black, they are made from just the black channel. Here are three similar colors. The third one uses colors other than black, but you may not notice just by looking at it.

…but if I turn off the CMY channels, it looks lighter than the other two…

There are times when you want to mix other colors into black to get what's called a rich black or 4-color black, but don't do that for this assignment.

You are adding to the confusion of OP. The professor means to use the CMYK colour mode with the C, M and Y components set to 0 and the K value anything between 10% and 90% (may be in 10% steps) in addition to 0% (white) and 100% (black).

That's your opinion.

Grayscale is a color mode (or color space) and not an effect.

Print file, CMYK color mode (though you will be limited to black and white,

To avoid confusion, it's worth noting that InDesign documents can not be assigned a single color mode. A page can have a mix of objects that have fills and strokes defined with different color modes (CMYK, RGB, or Lab).

When you fill or stroke an object with a percentage of the default [Black] swatch, you are using a CMYK color. InDesign has no Grayscale color mode or color space. You can't make a swatch defined as 50% Gray—it has to be a 0|0|0|50 CMYK mix.

You can place a grayscale mode image, but it is normally output to the CMYK black channel unless there is a forced color conversion when you output or export.

Transparency measures the opacity of an object, regardless of its colour or if it has a gradient.

A gradient is a blend from one colour to another (and possibly on to even more colours). Either or both or neither colour can be a greyscale value. Transparency can be applied to a gradient or not.

Greyscale Is just a percentage of process black used as a fill or stroke, as a colour in a gradient, or as the colour mode of a placed image.

Transparency can can be applied to a gradient. A gradient can be greyscale so long as all the colour values used in it are shades of process black.

IOW transparency, gradients, and greyscale are three different things.

None of the two. It's just a percentages of black:
