Options

A. 1
B. 2
C. 3
D. 4

Answer

A

Explanation

Summarise the information :
`PgtS`
`RgtT` and `RgtV`
O = T + 2
P = 62 or 63
If P is older than O then P is also older than T :
`{:("60 61 62 63 64 65"),(" P O T"):}`
Since P is older than S, and since R is older than V:
`{:("60 61 62 63 64 65"),("R V P O S T "):}`
So, if P is older than O, there is only one possible order in which the group could have been born.
