Option A has human, body systems and HIV, immune is absent.
Option B contains immune system and human, no HIV effects.
Option C contains HIV and immune system, no human.
All the options are lacking in some ways and will not produce the most relevant search results.
The correct option is D. It has all the necessary keywords.
When eating out it is important to take some measures in order to eat healthfully. It is important to avoid fried and grilled foods when eating out.

Hence, the correct answer is 'ordering meat dish that is grilled or broiled and avoid fried or breaded meat dishes'.

The table keeps track of all your data
401 of these offspring are expected to have long plumage.
To calculate the number of these offspring that are expected to have long plumage the following cross multiplication calculation must be performed:
- Total birds = 72 + 252 = 324
- Long plumage birds = 55 + 75 = 130
- 324 = 130
- 1000 = X
- 1000 x 130/324 = X
- 130000/324 = X
- 401.23 = X
Therefore, 401 of these offspring are expected to have long plumage.
