PHP - Output and String Handling

You want to print the following sentence exactly as it is, including the dollar sign:
The price's $price.
Which echo statement will produce this output correctly?

Aecho "The price's \$price.";

Becho 'The price's $price.';

Cecho "The price's $price.";

Decho 'The price's \$price.';

Step-by-Step Solution

Solution:

Step 1: Understand variable interpolation and escaping
In double quotes, $ starts variable interpolation. To print a literal $, it must be escaped with a backslash (\$).
Step 2: Analyze each option
echo "The price's $price."; prints "The price's " followed by $price (undefined, empty), resulting in "The price's .". echo 'The price's $price.'; syntax error due to unescaped apostrophe in "price's". echo "The price's \$price."; escapes $ correctly in double quotes (apostrophe fine), printing exactly. echo 'The price's \$price.'; syntax error from unescaped apostrophe (backslash literal if fixed).
Final Answer:
echo "The price's \$price."; -> Option A
Quick Check:
Escape $ in double quotes with \$ [OK]

Quick Trick: Escape $ with \$ inside double quotes to print it [OK]

Common Mistakes:

Not escaping $ in double quotes
Using backslash in single quotes incorrectly
Syntax error with unescaped apostrophe in single quotes
