As we have learned

Signal -

A single-valued function of time ( that conveys the information )

 It has at every instant of time a unique value.

 

 Thermometer 4 is transmitting multiple values of temperature from 3 Am to 12 PM. By definition , signal value at any given time ,however all other thermometers are transmitting a single value of temperature at any given point of time
