Which of the following are the core features of the Express framework?a.It is used to render the HTML pages dynamically.b.All of the mentionedc.It defines a routing table that can work as per HTTP Method and URL.d.It allows us to set up middleware to respond to HTTP Requests.

The core features of the Express framework include:

a. It is used to render the HTML pages dynamically: This is true. Express.js is a web application framework for Node.js that provides a robust set of features for web and mobile applications. One of these features is the ability to render HTML pages dynamically, which means the HTML content can change based on the data available at the time of rendering.

b. All of the mentioned: This option suggests that all the listed features are core features of Express.js. To confirm this, let's look at the other options.

c. It defines a routing table that can work as per HTTP Method and URL: This is also true. Express.js allows you to define a routing table, which is used to perform different actions based on the HTTP method (GET, POST, PUT, DELETE, etc.) and the URL that is requested.

d. It allows us to set up middleware to respond to HTTP Requests: This is another core feature of Express.js. Middleware functions are functions that have access to the request object (req), the response object (res), and the next function in the application’s request-response cycle. These functions can execute any code, make changes to the request and the response objects, end the request-response cycle, and call the next function in the stack.

So, the answer is b. All of the mentioned.
