Choose the correct answer from the options given below:

Solution

✅ Correct Option: 3

lx+my+nz=dlx + my + nz = d is the normal form of a plane (II). x/a+y/b+z/c=1x/a + y/b + z/c = 1 is the intercept form (IV). (r⃗−a⃗)⋅n⃗=0(\vec{r} - \vec{a}) \cdot \vec{n} = 0 is a plane through point a⃗\vec{a} with given normal n⃗\vec{n} (I). The combination with λ\lambda gives a plane through the intersection of two planes (III). So A-II, B-IV, C-I, D-III.
