The correct answer would be B, since complex sentences have 1 independent variable and one dependent variable.
The dependent variable would be: Everytime he hears a siren
Why? Because it is not a complete thought.
The independent variable would be: My dog howls loudly.
Why? This statement is a complete thought.
A would be a compound sentence
C would be a simple sentence
D would be compound complex.
