What will happen if we supply a voltage of 250 kV to the Vcc of the ESP8266 WiFi Module?

(a) Damage is caused

(b) Module will shut down

(c) Module will not respond for the time the voltage is applied

(d) Module will function normally

This question was addressed to me in an interview for internship.

The query is from ESP8266 Wifi Module topic in portion Interfacing of Sensors, Actuators, and Other Modules of Arduino

Best answer
Right option is (a) Damage is caused

The explanation is: The ESP8266 WiFi Modules are mostly built to work on a voltage of approximately 3.3V. Any voltage lower than that and the sensor will not be able to power on, but however any voltage significantly above that and the sensor may suffer permanent damage.
