What is d n e? given sets in photo

OPTION B: {5, 7, 9}

Step-by-step explanation:

D E is the collection of elements that are present in both D and E.

Given the set D = {5, 6, 7, 8, 9, 10}

and                 E = {1, 3, 5, 7, 9, 11}

So, the elements present in both D and E are: {5, 7, 9}.

Hence, D E = {5, 7, 9}.
