Step 1: Read the question and the given options carefully.

Step 2: Understand what a natural language processing (NLP) task is. NLP involves the interaction between computers and human language, allowing computers to understand, interpret, and generate human language.

Step 3: Examine each option and determine if it falls under the category of NLP task.

Option a) Image classification: This task involves categorizing images into different classes or categories. It does not directly involve processing human language, so it is not an example of an NLP task.
