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.

the attached picture
Option (b) and (f)i.e, Project Constellation and ExoMars have been deferred due to a shortage of funds and The amount of money spent on NASA is much less than the amount of money spent on the Department of Defense.
<h3>What Is NASA?</h3>
The National Aeronautics and Space Administration is known as NASA. The United States government's NASA agency is in charge of all air and space-related science and technology. With the Soviet satellite Sputnik's launch in 1957, the Space Age officially began.
On October 1st, 1958, NASA began operations. The organization was established to coordinate American space exploration and aviation research.
According to the study, the federal government spends 40 times less on NASA than on the Department of Defense. As a result, the initial response is correct. The second response is likewise accurate because it was stated clearly in the article. The other options are also illogical because neither Russia nor anybody else ever claimed that NASA or the government of Defense were less significant than one another.
Therefore, option(b)and(f) are the two claims.
