• B. Cross Cannizzaro's reaction
• C. Mixed Aldol condensation
• D. Aldol condensation

Answer 1

The correct option is B Cross Cannizzaro's reaction

It is given by the two different aldehydes having no $\alpha -H-$ atom in presence of $conc.NaOH$.
$(C{H}_3{)}_{3}C-CHO+HCHO\underset{NaOH}{\overset{Conc.}{\to }}(C{H}_3{)}_{3}C-C{H}_{2}OH+HCOONa$
