When radiation strikes an opaque surface part of it is:

a)absorbed
b)reflected
c)transmitted
d)all of the above
e)a and b
f)b and c
g) a and c

If I had to guess I would say it is absorbed and reflected but I'm not sure can someone help me out?

I'd go with that.
C, D, F and G are definitely out. Nothing is transmitted through opaqueness.
