State which of the following statement is true ?

A

The plane through the points A,B, C whose coordinates are `(1,1,1,),(1,-1,1) (-1,-3,-5)` respectively, passes though the point `(2, k, 4)` for all values of k.

B

The equation of the plane which is parallel to the plane `vecr .(2 hati-3 hatj+5 hatk)+7=0` and passing through the point (3,4,-1) is `vecr .(2 hati-3 hatj+5 hatk)+10=0`

C

The equation of the line of intersection of plane `3x+y+z=6 and x-y+2z=5`
`(4x-11)/(3)=(4y+9)/(5)=(z-0)/(1)`

D

The equation of a straight line `(x+3)/(2)=(y-4)/(3)=(z+5)/(2)` and the plane `4x-2y-z=1` are prependicular to each other
