Answer:
A) 1:1
Step-by-step explanation:
Each leg is the same value and the hypotenuse is 
of the value.
If a divides c,
then 'a' is a factor of 'c'.
Also,
If 'b' divides c,
then 'b' is also a factor of 'c'
therefore,
'a' and 'b' are factors of 'c'
Hence, a and b divides 'c'
so, c = a*b
and ab will also divide c.
Hence, proved.
