Which of the following is not an example of a virtual assistant?
- (a)Alexa
- (b)Cortana
- (c)Siri
- (d)Cortesa
Correct — D, Cortesa. Alexa (Amazon), Cortana (Microsoft), and Siri (Apple) are all real, widely-used AI-powered voice/virtual assistants. 'Cortesa' is not a real product from any tech company — it does not exist.
- (a)Alexa — Amazon's virtual assistant, which powers Echo smart speakers — a genuine, real-world example.
- (b)Cortana — Microsoft's virtual assistant, historically bundled with Windows — a genuine, real-world example.
- (c)Siri — Apple's virtual assistant, built into iOS and macOS devices — a genuine, real-world example.
Virtual (voice) assistants are AI-driven software agents that use natural language processing and speech recognition to carry out tasks or answer queries from spoken commands. Major real-world examples include Amazon's Alexa, Apple's Siri, Microsoft's Cortana, and Google Assistant — an everyday consumer application of AI.
The trap is an odd-one-out format: three genuine, well-known tech products are mixed with one fabricated, similar-sounding name. It tests basic awareness of which brand ships which assistant, and requires not assuming an unfamiliar name is real just because it fits the pattern.
- Alexa — Amazon's virtual assistant, powers Echo smart speakers
- Siri — Apple's virtual assistant, built into iOS/macOS
- Cortana — Microsoft's virtual assistant, was bundled with Windows
- Google Assistant is another major real-world example (not among this question's options)

- Assuming an unfamiliar-sounding option is real simply because it matches the naming pattern of the genuine ones (e.g., 'Cortesa')
- Confusing Cortana (Microsoft) with Siri (Apple) — both similarly-branded voice assistants
Odd-one-out format: three genuine tech products plus one fabricated name — tests basic tech/current-affairs awareness.
