Hey Satvik,
In ques 5. Ans is all of above…
I hope you understand that making ngram features is important. So bi gram or trigrams could be an option here.
Option C which is word2vec is a technique to convert a word to numeric features based on the context, this technique is often used with Textual data.
And Option A Topic Modeling is grouping together the features / sentences that have the same context.
Both these 2 techniques are used in textual data. You will learn about them in the later part of the course.

Thanks :slight_smile:
