The correct option is A I or II or III only

Solution

Option A is the correct answer

Statement 1

Sam's Present age $4+x$

Albert Age =$x$

Statement 2

$x=$20 ,

From statement $1$ and $2$ we get

$x=$24 years

From $1$ and $2$ we can find Sam and albert age after 5 years

Statement $3$ is not required.

From Statement $3$ and statement $2$ we ger

we can find out $x$ and $y$ hence there age after $5$ years

Statemnt 1 is not required

From Statement $1$ and $3$ we can find out x and y and hence Sam and Alber age after $5$ years .

Statement $2$ is not required

Hence either of three Statement $1,23$ is redundant.
