Each question in this section has four choices A , B, C , and D out of which only one is coR Rect. Mark your choices as follows .
Let R be a relation on the set `N N` of the natural numbers defined by nRm `ltimplies` n is a factor of m.
Let R be the relation over the set of integers such that mRn if and only if m is a multiple of n
Then R is reflexive because
A. mRn as m is multiple of n
B. mRn as m is multiple of m
C. mRn `cancelimplies` nRm
D. None of these
