Answer:
The best option to fill in the blank in the sentence "Colin doesn't have the correct _________ for that company." is:
**D. Web address**
The sentence would read: "Colin doesn't have the correct web address for that company."
Here's why the other options are less appropriate:
- **A. URL**: While a URL is technically correct, "web address" is more general and easier for a general audience to understand.
- **B. XYZ**: This is not contextually appropriate and doesn't fit with the idea of needing a specific piece of information about a company.
- **C. FBI**: This is irrelevant in the context of needing information about a company.
Thus, "web address" is the most appropriate choice for a general audience.
