In a computer language, a reserved word (also known as a reserved identifier) is a word that cannot be used as an identifier, such as the name of a variable, function, or label – it is "reserved from use". This is a syntactic definition, and a reserved word may have no meaning. So, B is incorrect.

Answer:
Explanation:
The following python code loops through each line within a file called text.txt and counts all the words, then it divides this count by the number of sentences in the text file. Finally, output the average number of words per sentence.
f = open("text.txt", "r")
all_words = 0
sentences = 0
for x in f:
list = x.split(' ')
all_words += len(list)
sentences += 1
average = all_words / sentences
print("There are an average of " + str(average.__round__()) + " words in each sentence.")
