Without ever declaring war, the world has been engaged in a pitched battle against coral reefs. From coral reefs that have been destroyed as a result of fishing with dynamite to coral reefs blanketed by and suffocating from sediment, fully two- thirds of these crucial ecosystems are under siege around the world. Approximately one-quarter of them have fallen a permanent casualty to modern assault weapons. Assailants are operative everywhere in the oceans. In addition to blast or dynamite fishing, other fishing methods, including bottom trawling and the practice of muroami, hitting the reefs with sticks to dislodge fish, are damaging reefs and destroying their delicate balance of life. Runoff consisting of pesticides, untreated sewage, and other contaminants that make their way to the reefs, which are typically not far from shore, operate like commandoes in surprise attacks on opponents. Abiotic factors, including water temperature, are also under attack as a result of global warming. In response to rising temperatures, corals eject the mutualistic and photosynthesizing algae called zooxanthellae, with which they exchange bene- fits and upon which their very existence relies.
1. The author most likely creates an extended analogy to war in order to

(B) make the topic more accessible through the use of a literary device.
(C) exploit a comparison between guerrilla warfare and ecosystem loss.
(D) couch the opening statistics within more comprehensible language.
(E) suggest the division of the audience into warring camps on the to pic of global warming.

(B) approximately one third of Earth’s coral reefs remain in pristine condition.
(C) approximately one quarter of Earth’s coral reefs are irretrievably lost.
(D) two thirds of Earth’s coral reefs lack the necessary defenses against pollution and other assaults.

1. The author most likely creates an extended analogy to war in order to
(A) illustrate the degree of destruction and the gravity of the problem facing coral reefs.
Looks correct. Hold on.
(B) make the topic more accessible through the use of a literary device.
The analogy does not help the details to be more accessible.
(C) exploit a comparison between guerrilla warfare and ecosystem loss.
No such comparison.
(D) couch the opening statistics within more comprehensible language.
The purpose is not to couch the statistics.
(E) suggest the division of the audience into warring camps on the to pic of global warming.
No such division suggested.
IMO A
2. In the passage’s first paragraph, the author asserts that
(A) certain sediments and fishing techniques are mainly responsible for the loss of Earth’s coral reefs.
No such emphasis.
(B) approximately one third of Earth’s coral reefs remain in pristine condition.
No such info.
(C) approximately one quarter of Earth’s coral reefs are irretrievably lost.
From the passage - Approximately one-quarter of them(reefs) have fallen a permanent casualty to modern assault weapons.
(D) two thirds of Earth’s coral reefs lack the necessary defenses against pollution and other assaults.
"two- thirds of these crucial ecosystems are under siege around the world." --> This does not imply that they lack the defenses.
(E) the undeclared war against coral reefs has been more destructive than many declared wars have been
No such emphasis.

I agree with the first two answers.
The answer to the third question , however, IMO is A.
The questions asks why according to the passage are zooxanthellae necessary.
Option C says Coral and zooxanthellae are interdependent. But that isn't the reason why zooxanthellae are necessary..
Option A. Loss of zooxanthellae affects the mechanism by which corals survive , therefore the loss of zooxanthellae upsets(affects) the coral reef ecosystem( broad term, includes coral reefs too). (correct IMO)
