Explain correlation coefficient of determination (R-square) and Adjusted R-square

A computer utility was applied to the data collected in a study of a generalized health index as a function of weight/ height/ ratio, cholesterol, and average nightly number of hours of sleep. Part of the output is shown below.

Independent variables	P-value	R2	Adjusted R2
WT/HT,CH,SLP	0.000	0.812	0.787
WT/HT,CH	0.000	0.801	0.784
WT/HT,SLP	0.000	0.792	0.775
CH,SLP	0.000	0.791	0.774
WT/HT	0.000	0.578	0.561
CH	0.000	0.667	0.654
SLP	0.000	0.699	0.687

Which single variable is the best predictor of generalized health?

a) Weight/height

b) sleep

c) cholesterol
