In amylose, $1,4-$glycosidic linkage is present.

So, this option statement is incorrect.

Sucrose has 1,2-glycosidic linkage between glucose and fructose. 

cellulose and amylose has$1,4-$glycosidic linkage. lactose contains$\mathrm{\beta }-\mathrm{D}-$galactose and$\mathrm{\beta }-\mathrm{D}-$glucose. maltose and lactose has$1,4-$glycosidic linkage.
