C. bg-blue-500 hover:bg-blue-700

Solution

1. Step 1: Identify the hover syntax error

   The class hover-bg-red-600 is invalid because Tailwind requires a colon after hover.

2. Step 2: Correct the syntax

   Changing it to hover:bg-red-600 fixes the hover styling.

3. Final Answer:

   The hover class should be hover:bg-red-600 with a colon. -> Option B

D. bg-gray-400 hover:bg-blue-600 focus:outline-4 focus:outline-yellow-400

Solution

1. Step 1: Identify required focus outline classes

   Tailwind uses focus:outline-4 for thick (4px) outline and focus:outline-yellow-400 for yellow color on focus.

2. Step 2: Check each option for correct order and completeness

   bg-gray-400 hover:bg-blue-600 focus:outline-4 focus:outline-yellow-400 includes the correct utility classes. Others use invalid syntax, wrong utilities, or zero width.
