Expert Solution
Step 1

Step:-1

Given domain is 3, 5, 6, 7, 10, 14, 20, 30, 60, 70 with relation is xy if x divides y

Option (a):-

Advanced Math homework question answer, step 1, image 1

we can see 1030 and 10 divides 30 but there is no path between 10 and 30 to show this relation.

Hence, this is not correct graph.

Option (b):-

Advanced Math homework question answer, step 1, image 2

As, we can see for each path between two vertices, the given relation is satisfied.

So, this option (b) is correct.
