Answer:
The correct option is A.
Step-by-step explanation:
From the given table it is noticed that the relative frequency of person who own fish and bird is 0.04 and the relative frequency of person who own fish but do not own bird is 0.08.
The total relative frequency of person who own fish is
[tex]0.04+0.08=0.12[/tex]
The sum of all relative frequency is 1.
[tex]0.04+0.08+0.02+0.86=1[/tex]
The % of the people surveyed own fish is
[tex]\frac{0.12}{1}\times 100=12\%[/tex]
Therefore the correct option is A.
