An alkyl halide with -hydrogen atom, when treated with a nucleophile/base, undergoes a substitution reaction or an elimination reaction, depending on the strength and size of the nucleophile/base and the reaction conditions. For the above reaction, the correct statement(s) is(are):

Options

1. AWhen A = CH ₃ ONa and B = HOH , Z with R =- CH ₃ is the major product.
2. BWhen A = ( CH ₃ )₃ CONa and B = ( CH ₃ )₃ COH , Y is the major product.
3. CWhen A = CH ₃ COONa and B = CH ₃ COOH , Z with R =- COCH ₃ is the major product.
4. DWhen A = CH ₃ ONa and B = CH ₃ OH , Y is the major product.
