Final answer:
The temperature in Gina's town was -5.03°C.
Step-by-step explanation:
Given that the temperature in Mika's town was -5.3 Celsius and in March town it was -4.06 Celsius, and in Tina's Town it was even colder than both of the other towns, we need to determine the possible temperature in Gina's town. The options are -2.6°C, -4.1°C, -5.03°C, and 5.4°C.
To find the temperature in Gina's town, we need to choose the value that is colder than the temperatures in Mika's town and March town. Therefore, the correct option would be -5.03°C.
