Option 4 : Dave

According to the given information,

1) Age of Alan = 34

2) As Alan is 2 years younger than Carl then,

Age of Carl = 34 + 2 = 36

3) Bob is one year younger than Carl

Age of Bob = 36 - 1 = 35

4)  Dave is two years older than Bob then, 

Age of Dave = 35 + 2 = 37

so, the order of their height would be 

 Dave > Carl > Bob > Alan.

So, the oldest person is Dave.

Hence, option 4 is the correct answer.
