You can look at this graph:     https://www.desmos.com/calculator/8albvsjxnd

 

And move the slider under  a  to see what happens as  a  gets smaller and bigger.

 

You should be able to see that as the value of  a  gets smaller, the parabola gets wider.

 

So you're right, the widest parabola is  c.  y = (1/8)x2    smiley
