Solution :
Both reactions will occur.
1) The first reaction is an example of enolate formation followed by SN2 reaction and finally hydrolysis to form the given monocarboxylic acid.
2) The second reaction is an example of elimination of aldehyde to form α-substituted product followed by elimination in presence of pyridine and heat to form α-β-unsaturated aldehyde. The complete reactions are provided below in the attached sheet.
