Explanation:

Here’s the thing: When it comes to error detection and correction in the OSI model, you want to look at the Data Link layer. Let’s break down each option so you can see why.

- Option 1: Transport Layer

Manages end-to-end communication, flow control, and error detection—but it’s mostly about error detection, not error correction. Think of it like checking if all the pieces arrived, but not fixing broken ones.

- Option 2: Data Link Layer

This is the layer that’s handling error detection and correction directly. It uses methods like checksums, CRC, and even Automatic Repeat reQuest (ARQ). So if a bit flips on the wire, this layer notices and fixes it.

- Option 3: Presentation Layer

Not its job. This one deals with data formatting, encryption, and translation—not transmission errors.

- Option 4: Application Layer

Completely out of scope. This layer manages what the user sees and interacts with, not the nitty-gritty of transmission errors.

So, if you picked Option 2—Data Link Layer—you nailed it.
