My DD and I thought the answer is A as both images on the left have Y shape in them just like A, C and E, but they are also a white cross with a half of the line stemming from the center (as opposed to the line going through the center.)

The answer sheet says C is the correct answer. Could someone explain the reason? Many thanks!

I got it. Silly me. I don't know how to delete the post...

I don't! why is the answer C?

Suspect it is a vertical line of reflection

Thanks!

How did you manage to get the picture of the problem question onto the screen?

I also want to ask a question but struggling to get the picture on the screen. Can you please help with that.

Have a look at FAQ number 4. You can only post a picture if it is available on the internet.

Regarding posting the picture, it has to be Internet. I uploaded it on Flicker and then used following instructions to get the URL:

https://help.flickr.com/en_us/get-the-u ... -S1Hnnmjym

Once you get the URL of your image, use the IMG tag (9th button from left above the box) and put the URL of image in that.
