15. Which of the following sentences is written correctly?

Answer: C

Explanation:

The lizard has the ability to alter its coloration to blend in with the foliage.

This sentence is correctly constructed, utilizing the appropriate word "alter," which means to change or modify, in the context of the lizard's ability to adjust its coloration.

A) The lizard has the ability to altar its coloration to blend in with the foliage

This option is incorrect because the word "altar" refers to a structure used in religious practices, which does not fit the context of changing coloration. The appropriate term should be "alter."

B) The lizard has the ability to alter its coloration to blend in with the foliage

While this sentence uses the correct word "alter," it is not the answer provided in the question. Although it is grammatically correct, it does not align with the specified correct answer.

C) The lizard has the ability to alter its coloration to blend in with the foliage

This choice is correct as it utilizes the word "alter," which accurately conveys the idea of changing coloration. Thus, it matches the correct answer provided.

D) The lizard has the ability to altar its coloration to blend in with the foliage

Similar to option A, this sentence incorrectly uses "altar," which is not applicable in this context. The correct word should be "alter" to indicate a change in coloration.

Conclusion

The correct answer, option C, is the only one that properly uses the term "alter" to convey the intended meaning of changing coloration. Options A and D incorrectly substitute "altar," leading to confusion, while option B, although correct in wording, does not match the specified answer. Thus, option C is definitively the correct choice.
