Write the equation of the regression model.

A) Weight = -285.21 - 1.3838 Age - 11.24 Head Width + 28.594 Neck
B) Weight = 78.45 - 0.9022 Age - 20.88 Head Width + 5.870 Neck
C) Weight = 132425- 44142 Age - 41.81 Head Width + 0.002 Neck
D) Weight = -285.21 + 78.45 Age - 3.64 Head Width + 0.022 Neck
E) Weight = -3.64 - 1.53 Age - 0.54 Head Width + 4.87 Neck

The correct equation of a regression model typically includes a constant term and coefficients for each variable that represent the relationship between the dependent variable (in this case, Weight) and each of the independent variables (Age, Head Width, Neck). Choice A is the most plausible as it follows the general structure of a regression equation, with a constant term and coefficients for each variable that seem reasonable for a model predicting weight based on age, head width, and neck circumference.
