You Answered:

Selection BA pre-specified model with main effects for 3 predictors, supplemented with 2 important interaction terms

INCORRECT

The correct answer is the stepwise selected model described under (c). The bias is lowest for this model, which most closely describes patterns in the data set under study. However, the variability may be quite large when this model is based on a small data set.
