Country first unmanned tank, developed by an Indian defence laboratory in Chennai, was rolled out under which name?

Introduction / Context:
Defence technology developments, especially first in the country achievements, are common topics in general awareness. An unmanned tank is an armoured vehicle that can be remotely operated, reducing risk to soldiers in dangerous environments. India first such unmanned tank was developed by a defence laboratory in Chennai and received a specific name, which you are expected to remember.

Given Data / Assumptions:

- The question refers to the country first unmanned tank.

- It was developed in a defence laboratory located in Chennai.

- The options are Muntra, Lira, Santra and Myntra.

- We must select the correct name of this unmanned tank.

Concept / Approach:
The Defence Research and Development Organisation developed an unmanned tank called Muntra, designed for operations such as mine detection and nuclear or chemical contamination monitoring. The name Muntra stands out among the options because Lira and Santra sound more like generic words, and Myntra is a well known online fashion portal, not a defence platform. Associating Muntra with unmanned tank and Chennai laboratory is the best way to remember this fact.

Step-by-Step Solution:
Step 1: Note that the question is about an unmanned, remotely operated tank developed in India. Step 2: Recall that news reports highlighted Muntra as the name of this first unmanned tank being rolled out from a Chennai lab. Step 3: Compare the options and eliminate Myntra, which you may know as an e commerce brand unrelated to defence. Step 4: Recognise that Lira and Santra do not have any known connection to Indian unmanned tank development. Step 5: Conclude that Muntra is the correct name and select it.

Verification / Alternative check:
If you recall watching defence news or reading about India first unmanned tank, you might remember that multiple variants were mentioned, such as Muntra S and Muntra M, aimed at different roles. This naming pattern is a strong cue that Muntra is indeed the unmanned tank platform developed in the Chennai based Combat Vehicles Research and Development Establishment.

Why Other Options Are Wrong:

Option B (Lira) is the name of a currency and does not relate to Indian armoured vehicles.

Option C (Santra) is a common word for orange fruit in some Indian languages and has no connection to defence platforms.

Option D (Myntra) is a popular fashion e commerce site and appears as a distractor here.

Common Pitfalls:
Candidates sometimes get confused by similar sounding names or by brand names they have heard more frequently, such as Myntra. To avoid this, always link defence platforms with their role and organisation, for example Muntra with unmanned tanks and DRDO. Maintaining a list of first in India defence projects can also make revision easier.

Final Answer:
The correct answer is Muntra, the name given to the country first unmanned tank developed in a Chennai defence laboratory.
