Final answer:
A Bronsted-Lowry acid is a proton donor and is often symbolized as HA.
Step-by-step explanation:
A Bronsted-Lowry acid is a proton donor. It is often symbolized as HA. This means that it donates a proton (H+) to another molecule or ion that acts as a base. The reaction can be represented as:
HA + B ⟶ A- + BH+
Here, HA is the acid (proton donor) and B is the base (proton acceptor). So, the correct answer is A)True.
