If `A = {x||x in N,x` is a prime number less than 12} and `B = {x|| x in N , x ` is a foctor of 10} then `A nn B =`….

Options

A. `{2}`
B. `{2,5}`
C. `{2,5,10}`
D. `{1,2,5,10}`

Answer

B

Explanation

We have
` A= {x|x in N, x|` is a prime number less than 12}= {2,3,5,4,11}
and B = {x|x` in ` N , is a factor of 10 } = {1,2,5,10}
`therefore A nn B = {2,5)`
