Which state government inaugurated the upgraded version of the police emergency helpline Namma 100, promising to send officials to the spot of emergency within 15 minutes?

Introduction / Context:
This question tests your knowledge of Indian state level initiatives for public safety and emergency response. Many state police departments operate modern helpline numbers that integrate call centres, patrol vehicles and technology. The upgraded Namma 100 helpline with a fifteen minute response promise was a notable reform and became a favourite topic in current affairs sections of competitive exams, especially for aspirants from southern India.

Given Data / Assumptions:
- The question mentions a police helpline called Namma 100.
- It asks which state government inaugurated an upgraded version with a target of reaching the emergency spot in fifteen minutes.
- The options are Karnataka, Telangana, Tamil Nadu, Madhya Pradesh and Kerala.

Concept / Approach:
The key concept is to associate unique names and branding with particular states. The word Namma means our in Kannada and is often used in Karnataka for branding initiatives such as Namma Metro and Namma Bengaluru. Recognising regional language clues is a powerful method to solve many state specific current affairs questions even when you do not recall the exact news article or date.

Step-by-Step Solution:
Step 1: Observe the helpline name Namma 100 and identify the language family of the word Namma. Step 2: Recall that Namma Metro is the brand name of the metro rail system in Bengaluru, which is the capital of Karnataka. Step 3: Connect the repeated use of Namma as a local identity word with the Karnataka government. Step 4: Note that other southern states have their own terms and branding and do not typically use Namma in official scheme names. Step 5: Conclude that the upgraded police helpline Namma 100 with a fifteen minute response promise belongs to Karnataka.

Verification / Alternative check:
Another quick verification method is to recall that Bengaluru city police and Karnataka state police have both promoted Namma 100 as a modern integrated response system. Media coverage often highlighted the use of GPS enabled vehicles and monitoring rooms in Bengaluru. No such consistent association exists between Namma 100 and the other states listed. Therefore, the identification of Karnataka remains solid even after cross checking.

Why Other Options Are Wrong:
Telangana has Hyderabad city police and uses different names for its helpline services, not the brand Namma 100.
Tamil Nadu runs its own police control room numbers but does not typically use Namma in Tamil branding, where Nam refers to us but is not used in this exact way.
Madhya Pradesh is a central Indian state with its own emergency helplines and branding, unrelated to Namma 100.
Kerala also has separate emergency numbers and local names but is not connected to this specific Namma 100 scheme.

Common Pitfalls:
A common mistake is ignoring the language clue and guessing based only on popularity of states. Some students also misremember that because Hyderabad has advanced policing, Namma 100 must be from Telangana. Others focus only on the number 100 and forget to interpret the word Namma. In reasoning and verbal questions, close attention to small words that indicate region or language often makes the difference between a correct and incorrect answer.

Final Answer:
The upgraded police helpline Namma 100 with a fifteen minute response target was launched by the state government of Karnataka.
