The correct option is D None of these
Clearly direction ratios of perpendicular drawn from origin to the given plane are 3,4,−6
Hence equation of perpendicular line to the given plane and passing through origin is given by,
x3=y4=z−6=k (say)
Now let foot of perpendicular be P(3k,4k,−6k)
Also this point lie in the given plane ⇒3(3k)+4(4k)−6(−6k)+1=0⇒k=−161
Hence P≡(−361,−461,661)
