Following is a correlation matrix of a dataset on the power generation data of a combined cycle power plant. Which is a correct inference that can be drawn from this matrix?


Ambient temperature

Exahaust vacuum
Atmospheric pressure
Relative humidity
Power output
Ambient temperature
1.000000 0.844107 -0.507549 -0.542535 -0.948128
Exahaust vacuum
0.844107 1.000000 -0.413502 -0.312187 -0.869780
Atmospheric pressure

-0.507549 -0.413502 1.000000 0.099574 0.518429
Relative humidity
-0.542535 -0.312187 0.099574 1.000000 0.389794
Power output
-0.948128 -0.869780 0.518429 0.389794 1.000000

A.
Low relative humidity is likely to increase the power output


B.
The power output should be higher for a higher ambient temperature


C.
Exhaust vaccum has little or no effect on power output


D.
The power output should be higher for a higher atmospheric pressure
