Which of the following statement is correct?

According to Bronsted-Lowry theory, an acid is a substance that can donate proton $\left(H^{+}\right)$ while a base is a substance that can accept proton $\left(H^{+}\right)$. $BC{l}_3$ cannot donate a proton since it doesn’t have any proton in it & therefore Bronsted - Lowry theory could not explain the acidic nature of $BC{l}_3$ but it is a good Lewis acid as it can accept an electron pair.
