    so the answer is D? ..but why how come its not a translation but rather a reflection? can you explain please?

    if you look in a mirror what do you see?

    a relection...but it also looks like a translation...

    a translation is when you take something and move it elsewhere so efectivly a reflection is also a translation.

    the answer is B. B. vertical translation of 10 units. It cannot be a reflection, note that H has a vertex at (4,2) and the reflection about X-axis will have vertex at (4,-2) but the figure H prime (the bottom one) has a vertex at (4,-3). Thus on reflection the figures won't overlap. Only way to do that is to slide down the figure above 10 units to the bottom.

    it cannot be a reflectio cuz, in mirror if u see, preimage is at same distance from the image. but here thats not the case..

    okay...I see what you mean about the reflection @pitankar and @ganeshie8

    it does look like a reflection cuz it has horizontal symmetry.. if it was translated just 9 units down, then its both translation and reflection
