1:09:05 sir correct answer is option a only reflexive

[@MohanaPriya-qn1rm]

Yes, he's right

[@Abhi-w9b]

But x/2 should be less than x so it is not reflexive as sir said in starting y>or equal to x

[@abouttech7728]

Sir Homework : Both reflexive and symmetric so sir ek matrix bana liya A*A kyunki reflexive hai to diagonal to aayega hi relation mai For symmetric(Considering with respect to upper triangle) : ham kisi bhi ek element in upper triangle ko leyenge to uske corresponding ek element lower triangle wala aajayega so ham kisi bhi upper triangle wale element ko le sakta hai ya nahi le sakta baki kaam ho jayega so 2 choices per element of upper or lower triangle . Total no. of element in matrix = n**2 no. of element in diagonal is n no. of element in each triangle equal as square matrix so no. of elements are (n**2-n)/2 So number of relations are 2 raised to power (nsquare - n)/2
