The correct answer is D. Noah Webster's contributions resulted from his interest in politics and his concern for language.
Explanation:
Webster was a pioneering lexicographer, and his books on grammar and spelling, such as the A Grammatical Institute of the English Language (1783–1785) and the American Dictionary of the English Language (1828), standardized American English. The latter dictionary is still published in new, extended editions, and is the major standard dictionary in the United States. Among the changes he introduced in American English was to change, -RE to -ER in words such as theater, to abolish one L in words like traveling and the U in words like color.
