(a) If both A and R are true and R is the correct explanation of A

(b) If both A and R are true and R is not the correct explanation of A
(c) If A is true but R is false
(d) If A is false but R is true
1. Assertion (A): Speech Recognition technology is a core component of Voice User Interfaces (VUIs).
Reason (R): NLP plays a crucial role in understanding and responding to spoken commands in
applications such as Siri and Google Assistant.
2. Assertion (A): Converting the entire text into lowercase following stop word removal is a crucial pre-
processing step in natural language processing.
Reason (R): This process ensures uniformity in word representation, preventing the machine from
treating words with different cases as distinct entities, thereby enhancing the accuracy of subsequent
text analysis.
3. Assertion (A): Removing stopwords improves NLP model efficiency.

Reason (R): Stopwords like “is”, “the”, and “in” add significant meaning to text processing.
