Build a Survey Form-HELP WITH IMAGE LOGO AND CHECKBOX

Dear Campers,
I passed in my survey project but there is some error in my alignment for the following:
my checkbox is coming a bit centered and not in the same alignment like my radio.
Secondly, if you notice the labels in row tab to the left of my input, (radio and suggestion/feedback) , are not centered to the inputs as it should be but rather they are coming out to the bottom of the alignment on the row tab.
Thirdly, I am unable to include a logo in my header : when I tried doing so, it either does not show up or shows up fully in the background.

All suggestions are invited to fix the above issues.Whats the mistake in my following code?
Thanks so much
