(A) The first reaction is: $4BF_3 + 3LiAlH_4 \xrightarrow{(C_2H_5)_2O} 2B_2H_6 + 3LiF + 3AlF_3$. Here,$X$ is $B_2H_6$ (diborane).The second reaction is: $B_2H_6 + 2NaH \longrightarrow 2NaBH_4$. Here,$Y$ is $NaBH_4$ (sodium borohydride).$NaBH_4$ contains the $BH_4^-$ ion,where hydrogen is in the $-1$ oxidation state.$NaBH_4$ is a well-known reducing agent,not an oxidizing agent.Therefore,the statement 'It is a good oxidizing agent' is incorrect.

Observe the following reactions (not balanced):
$BF_3 + LiAlH_4 \xrightarrow{(C_2H_5)_2O} X + LiF + AlF_3$
$X + NaH \longrightarrow Y$
The incorrect statement about $Y$ is:
