Answer:
The correct answer is B. The Union's main strategy during the Civil War was to blockade all major southern ports. It was called the "Anaconda Plan", and was proposed by Major General Winfield Scott. It emphasized the blockade of the ports in the south, and added an advance down the Mississippi River to divide the Confederate states into two. Since the blockade would be rather passive, it was ridiculed by those who wanted more active warfare. But at the end, the blockade prooved to be effective, and people compared it to the bowels of an anaconda that suffocated its victim.
