Consider the following pseudocode that returns an Optional value from a method:
if there is a result // line 1
return the result // line 2
else
return an empty result // line 3
Assume that the variable result represents an object reference to the result to be returned as Optional.Replace line 1 with the Java code to determine whether there is a result.
A)if (result.ifPresent())
B)if (result == null)
C)if (result != null)
D)if (result.isPresent())
