If site Bran were buried more deeply and compacted over time, how would its porosity and rock stability likely change?

As burial depth increases, the weight of overlying sediment presses the grains together. Compaction closes some pore spaces, so porosity decreases, and the tighter packing generally makes the rock more stable. Therefore, the correct choice is “Porosity would decrease, and rock stability would increase as pore spaces close under pressure.”
