An electron, a doubly ionized helium ion `(He^(+ +))` and a proton are having the same kinetic energy . The relation between their respectively de-Broglie wavelengths `lambda_e , lambda_(He^(+)) + ` and `lambda_p` is :

Options

A. `lambda_e gt lambda_(He^+) + gt lambda_P`
B. `lambda_e lt lambda_(He^+) + = lambda_P`
C. `lambda_(e) gt lambda_P gt lambda_(He^+) + `
D. `lambda_(e) lt lambda_P lt lambda_(He^+) + `
