Answer: (B)

The primary goal of Sentiment Analysis in text processing is to quantify sentiments, which involves determining the emotional tone behind a body of text. This is typically achieved by analyzing word frequencies and identifying patterns that indicate positive, negative, or neutral sentiments within the text. By using various techniques such as natural language processing and machine learning, practitioners can assess how individuals feel about a given topic based on the language used in their expressions, reviews, or feedback. Focusing on word frequencies allows for an objective measurement of sentiment, enabling businesses and researchers to gauge public opinion, monitor brand reputation, and improve decision-making based on emotional responses. This quantitative approach is fundamental to sentiment analysis, making it a valuable tool in fields such as marketing, product development, and customer engagement.
