Answer:
The correct option is B)
and 
Step-by-step explanation:
given 
Since, 
it means prependicular of right angled triangle can be calculated by pythagoras theorem as:
base² + prependicular² = hypoteneous²
2² + prependicular² = 3²
4 + prependicular² = 9
prependicular² = 9 - 4
prependicular² = 5
prependicular = √5
Since, 

Since, 

Hence, the correct option is B)
and
