Assume you are using R studio to create a model (energyusage) in which consumption is the dependent variable and temperature, insulation, and othervariable are the predictive variables. Which command would you use to create a histogram of the variable the model is trying to predict?

a) > hist(energy_usage$consumption)

b) > hist(energy_usage$othervariable, temperature, insulation)

c) > histogram(energy_usage)

d) > summary(energy_usage)
