(b) Angular momentum and work
(c) Energy and moment of inertia
(d) Light year and wavelengths
(1) a and b
(2) a and d
(3) b and c
(4) a, b, and d
with explanation plzz​

Answer 1

(4) a , b , & d

because

Dimentional formula of:

Torque and work are - [L2M1T(-2)]

Light year and wavelength are - [L1M0T0]

Angular momentum and work are -

[L2MT -1]
