Answer 1

Answer:

 

The correct answer was given: nikhil3810rhmschool

the correct option is c) (y, z)

step-by-step explanation:

x is a factor of y

⇒ l.c.m. of x and y = x

y is a factor of z

⇒ l.c.m. of y and z = y

also, l.c.m. of x and z = x

and l.c.m. of x, y and z = x

so, the required pair of set has l.c.m. y = y and z

therefore, the correct option is c) (y, z)
