To determine what percentage of the people surveyed own fish, follow these steps:

1. Identify the relevant data from the table:
- The percentage of people who own both a bird and a fish is [tex]\(0.04\)[/tex] (or 4%).
- The percentage of people who do not own a bird but do own a fish is [tex]\(0.06\)[/tex] (or 6%).

2. Calculate the total percentage of people who own fish:
- To find the total percentage, we need to add the two percentages together:
[tex]\[ 0.04 + 0.06 = 0.10 \][/tex]
This gives us a total of [tex]\(0.10\)[/tex] (or 10%).

3. Convert the total to a percentage:
- [tex]\(0.10\)[/tex] as a percentage is [tex]\(10\% \)[/tex].

Therefore, the percentage of the people surveyed who own fish is [tex]\( \boxed{10\%} \)[/tex].

So, the correct answer is:
D. [tex]\(10 \%\)[/tex]
