Physical models can represent objects or systems that are too small, too big, or too far away to study. They are way easier, cheaper, and safer to work with or use when compared to the real objects that they represent.
Explanation:
The answer is B

14 carbon atoms do the 14CO2 used to synthesize malonyl-COA from acetyl-CoA appear in palmitate.
Acetyl-CoA is carboxylated into malonyl-CoA by the acetyl-CoA carboxylase enzyme. The joining of one acetyl-CoA molecule and one bicarbonate molecule requires energy from ATP.
Malonyl coenzyme A: acyl carrier protein transacylase is an enzyme that uses malonyl-CoA in the production of fatty acids (MCAT).
The highly controlled acetyl-CoA carboxylase (ACC) in the cytoplasm produces malonyl-CoA by carboxylation acetyl-CoA in biotin and ATP-dependent manner. Acetyl-CoA carboxylase is an enzyme that changes acetyl-CoA into malonyl-CoA. Malonyl-ACP is created when the malonyl group is added to an acyl carrier protein.
A condensation reaction between malonyl-ACP and acetyl-CoA results in acyl-ACP and the simultaneous release of CO2.

I would say B but yea hopefully it’s right I’m pretty sure it is though
