Answer : 1. "Vehicle thefts"
Explanation :

The central government has decided to implement microdot technology to investigate incidents of vehicle theft in the country. Under this, automobile manufacturers will be asked to spray thousands of tiny laser dots with the vehicle identification number all over the vehicle, including the engine. This way, it will be easy to track any vehicle at any time. As of now, more than 2 lakh vehicles are stolen in India every year, with Delhi at the top position in such cases.
