Statement-$1$ is true,Statement-$2$ is false.

(C) Orthoboric acid,$H_3BO_3$ (or $B(OH)_3$),acts as a weak monobasic Lewis acid in water.It does not donate a proton $(H^+)$ directly; instead,it accepts a hydroxyl ion $(OH^-)$ from water to release a proton.The reaction is: $B(OH)_3 + 2H_2O \rightleftharpoons [B(OH)_4]^- + H_3O^+$.Since it acts as a Lewis acid (electron pair acceptor) rather than a Brønsted-Lowry acid (proton donor),Statement-$1$ is true and Statement-$2$ is false.
