JEE Advanced 2024 Physics question on Units and Measurements

A dimensionless quantity is constructed in terms of electronic charge ee, permittivity of free space ε0\varepsilon_0, Planck's constant hh, and speed of light cc. If the dimensionless quantity is written as eαε0βhγcδe^\alpha \varepsilon_0^\beta h^\gamma c^\delta and nn is a non-zero integer, then (α,β,γ,δ)(\alpha, \beta, \gamma, \delta) is given by
