Leading communication app Truecaller tied up with which company to integrate the video calling app Duo within the Truecaller application?

Introduction / Context:
This question deals with digital applications and technology partnerships. Truecaller is a popular communication app used for caller identification and spam blocking. The question refers to a collaboration in which Truecaller integrated a video calling feature from another tech giant s app called Duo. Knowing which company owns Duo helps answer the question.

Given Data / Assumptions:

• Truecaller is the communication app mentioned.
• The integrated video calling app is named Duo.
• The tie up is with a large technology company that owns Duo.
• The options list several major Indian and global technology companies.

Concept / Approach:
Duo is a video calling service developed by Google. When Truecaller announced a partnership to provide direct video calling from within its app, it chose to integrate Google Duo. Therefore, the correct answer is the company that owns Duo, which is Google. The other listed companies do not have a product called Duo and were not part of this particular partnership.

Step-by-Step Solution:
Step 1: Recall that Duo is a simple video calling app launched by Google to compete with other video chat services. Step 2: Note that Truecaller wanted to expand beyond caller ID to offer direct video calling to its users. Step 3: Recognise that the integration allowed users to initiate a Duo call from inside Truecaller if both parties had Duo installed. Step 4: Identify from this information that the partner company must be Google, the owner of Duo.

Verification / Alternative check:
Official blog posts from Truecaller and announcements from Google at the time confirm that the two companies partnered to integrate Google Duo into Truecaller. Technology news sites also reported this collaboration, clearly naming Google as the partner. None of the other companies in the options were associated with the Duo video calling service.

Why Other Options Are Wrong:
Infosys and TCS: These are major Indian IT services companies and do not own consumer video calling apps called Duo. Facebook: While it operates multiple communication platforms such as WhatsApp and Messenger, Duo is not one of its products. Microsoft: Microsoft has Skype and other services, but the app called Duo is not its creation and was not the one integrated with Truecaller.

Common Pitfalls:
A common mistake is confusing Duo with other video apps like Skype or WhatsApp and then selecting the company linked to those services. Some examinees also choose a large Indian IT company simply because Truecaller has many users in India. The safe approach is to directly link the brand Duo to Google and then pick the corresponding option.

Final Answer:
Truecaller partnered with Google to integrate the Duo video calling app into its platform.
