Explanation:

Step1: Read stem - and - leaf plot

In a stem - and - leaf plot, the stem represents the tens digit and the leaf represents the units digit.
For stem \(3\), leaf \(9,9\) gives \(39,39\).
For stem \(4\), leaf \(2,3,3,4,6,7,9\) gives \(42,43,43,44,46,47,49\).
For stem \(5\), leaf \(0,1,5,6,7\) gives \(50,51,55,56,57\).
For stem \(6\), leaf \(0,5,5\) gives \(60,65,65\).

Answer:

B. \(39, 39, 42, 43, 43, 44, 46, 47, 49, 50, 51, 55, 56, 57, 60, 65, 65\)
