Model Answer

(C) Text Classification

Text Classification categorizes documents into predefined groups, which is how spam filters sort emails into "spam" or "not spam" categories.

Explanation

The textbook defines Text Classification as a tool that "classifies a sentence or document category-wise" into predefined groups. Spam filtering works by classifying incoming emails into categories (spam/not spam), making Text Classification the correct answer. Virtual Assistants relate to voice processing, Sentiment Analysis detects emotions/opinions, and Automatic Summarization condenses text — none of these match spam filtering.
