Answer:
Option K
m is an odd integer and n is an even integer
Step-by-step explanation:
The sum of intergers when one is even and another is odd results into an even number. Take for example, if x is even and the next number x+1 their sum will be 2x+1. The presence of +1 at the end shows the number is not divisible by 2 hence an odd number.
Practically, if you add 2+3=5 and 2 is even number while 3 is odd, clearly the sum being 5 is an odd number.
Otherwise, if you add two even numbers or two odd numbers the sum will be an even number.
Yes it is true that point , line and pair of intersecting lines are special cases of conic sections
They are actually degenerate cases of intersection that occurs in special conditions.
Lets get into a bit detail one by one
A single point - when the plane which cuts the surface of cone only passes through apex
Again when the plane passes through apex and another point on the cone
it produces one straight line or two intersecting straight lines.
