Answer:
Option A is correct
Step-by-step explanation:
If they are perpendicular to a common line then they must be parallel to each other.
m 1 =p(p 2 +1)
m 2= (p ^2 +1)
(p^2+1) 2=−(p ^2 +1)
m 1 =m 2
p(p2 +1)=−(p 2 +1)
∴p=−1
Hence The lines are perpendicular to a common line forexactly one value of p
