Right option is (a) Diagonals lines

Best explanation: The temperature read by the thermometer where the bulb of thermometer is enclosedwith a wet cloth is called as wet bulb temperature. If the reading of the wet bulb temperature is lower, this indicates that the surroundings have lower humidity.When the relative humidity is 100%, then wet bulb temperature is equal to the air temperature.
