a) Continuous. (Because 'time taken to elevate heart rate' can take any integer value and in between those values in seconds)
b) Discrete. (Because number of crime can only be an integer)
c) Continuous. (Square ft. of empty space can take any value, even between integer values)
d) Discrete. (Number of voters can only be an integer value)
