ColdFusion Markup Language (CFML) basics: Which statement about CFML is accurate for modern web development using Adobe ColdFusion/Lucee? Choose the best option that reflects how CFML pages work inside regular HTML documents.

Introduction / Context:
ColdFusion Markup Language (CFML) is a server-side scripting language used to build dynamic web applications. CFML files intermix HTML with CFML tags and expressions, much like other templating technologies. A common point of confusion is whether CFML runs in the browser, which file extensions it uses, and how tags are defined.

Given Data / Assumptions:

• CFML pages are typically saved with .cfm or .cfc extensions and processed by a ColdFusion/Lucee server.
• Browsers receive plain HTML, CSS, and JavaScript, not CFML code.
• CFML employs a rich, tag-based syntax and supports user-defined custom tags.

Concept / Approach:

CFML works by embedding tags (for example, , , ) directly alongside standard HTML. The application server parses these tags on the server, executes business logic or database operations, and then returns rendered HTML. Developers can also create custom CFML tags (user-defined tags or components) and invoke them inline within HTML markup, which is a hallmark feature of CFML templating.

Step-by-Step Solution:

Verification / Alternative check:

Inspect a typical .cfm page; you will see tags like and embedded in HTML. When requested, the server renders HTML to the client, verifying server-side execution and tag usage.

Why Other Options Are Wrong:

.asp files belong to ASP/ASP.NET, not CFML.

CFML is not executed on the client; it is rendered to HTML on the server.

CFML absolutely uses tags; that is its defining syntax.

Common Pitfalls:

Confusing CFML with client-side JavaScript; assuming file extensions from other stacks; forgetting that CFML custom tags can encapsulate reusable server-side functionality.

Final Answer:

It allows for coding of custom tags in an HTML file.
