A vector is given by `A=4hati + 3hatj + 5hatk`, where `alpha, beta and gamma` are the angles made by A with coordinate axes. Then, match the Column I with Column II (respective values) and select the correct option from the codes given below.
Column I Column II
A. `alpha` p. `cos^(-1) (1'/'sqrt2)`
B. `beta` q. `cos^(-1) (4'/'5sqrt2)`
C. `gamma` r. `cos^(-1) (3'/'5sqrt2)`
Options:
(a) A-p B-q C-r (b) A-q B-r C-p (c) A-r B-q C-p` (d) `A-p B-P C-q
