Cool weather typically weakens muscle power in cold-blooded creatures. In the veiled chameleon, a cold-blooded animal, the speed at which the animal can retract its tongue declines dramatically as the temperature falls. However, the speed at which this chameleon can extend its tongue does not decline much as the temperature falls.

"Surprising" Phenomenon
Why is the chameleon’s tongue extension speed largely unaffected by temperature drops while the weakened muscle power resulting from such drops dramatically slows the chameleon’s tongue retraction speed?

Objective
The right answer will describe a key difference between chameleon tongue retraction and chameleon tongue extension. That difference must explain why tongue retraction speeds decrease dramatically in lower temperatures while tongue extension speeds remain largely unchanged. The answer will likely explain why tongue extension is less impacted than retraction by the muscle weakening chameleons experience in lower temperatures.

A
Most cold-blooded animals are much more active in warmer weather than in cooler weather.
This doesn’t help us. We need information about a difference between chameleon tongue extension and chameleon tongue retraction. It doesn’t matter how active most cold-blooded animals are in different weather.
B
Many cold-blooded animals, including the veiled chameleon, have tongues that can extend quite a distance.
This doesn’t help us. We need information about a difference between chameleon tongue extension and chameleon tongue retraction. The distance the tongues extend doesn’t matter.
C
Veiled chameleons are found in a wide range of habitats, including ones with wide variations in temperature and ones with moderate climates.
This doesn’t help us. It doesn’t matter which climates chameleons live in; we only care about a difference that emerges in low temperatures, whether or not chameleons are often found in various habitats.
D
In the veiled chameleon, tongue retraction is powered by muscles, whereas tongue extension is driven by energy stored in a rubber band-like sheath.
This explains why chameleon tongue extension is considerably less impacted than tongue retraction by temperature drops. The muscle weakening chameleons experience in cold temperatures affects tongue retraction but not extension, because extension is not powered by muscles.
E
Compared with the muscles in the tongues of most cold-blooded animals, the retraction muscles in the veiled chameleon’s tongue are considerably stronger.
This doesn’t help us. We need information about a difference between chameleon tongue extension and chameleon tongue retraction, not a difference between the chameleon’s tongue muscles and other cold-blooded animals’ tongue muscles.
