A

Statement 1 is false 2 is true

B

Statement 1 is true, statement 2 true , statemens 2 is a correct explanation for statement 1

C

Statement 1 is true, statement 2 is true: statement 2 is not a correct explanation for statement 1

D

Equation of tangent to the ellipse `(x^(2))/(2)+(y^(2))/(4)=1` is
`y=m x(4sqrt(3))/(m) " "(1)`
Equation of tangent to the parabola `y^(2)=16sqrt(3)x` is
`y=m x+(4sqrt(3))/(m)" "(2)`
On comparing (1) and (2)
`rArr48=m^(2)(2m^(2)+4)rArrm^(4)+2m^(2)-24=0`
`rArr(m^(2)+6)(m^(2)-4)=0rArr m^(2)=4rArr m=+-2`
So, equation of commn tangents are
`y=+-2x+-2sqrt(3)`
Statement 1 is true
Statement 2 is obviously true and correct explanation of statement 1
