To determine which sentence is punctuated incorrectly, we need to review the punctuation rules. In this case, we're looking for a sentence where the punctuation is used incorrectly.

Let's examine each option:

a. "Remember to turn off the lights and lock the door." - This sentence appears to be punctuated correctly. It has a period at the end since it is a statement.

b. "On our trip we will be driving, and taking the train." - This sentence uses a comma before the coordinating conjunction "and" to connect the two verbs "driving" and "taking." This is the correct use of punctuation.

c. "Fred will feed the cat, and Rose will pick up the mail." - This sentence also uses a comma before the coordinating conjunction "and" to connect the two subjects "Fred" and "Rose." This is the correct use of punctuation.

d. "The weekend was short but fun." - This sentence appears to be punctuated correctly. It has a period at the end since it is a statement.

After analyzing each option, it seems that there is no sentence that is punctuated incorrectly. Therefore, the answer is none of the options, and all the sentences are punctuated correctly.

The sentence that is punctuated incorrectly is sentence b. On our trip we will be driving, and taking the train.
