Is the following informal command grammatically correct?

Question:

Decide if the following informal command is grammatically correct or incorrect. no di mentiras.

a. correct
b. incorrect

Answer:

The correct answer is b. incorrect

Explanation:

When analyzing the command "no di mentiras," it is important to understand the components of the sentence. The informal command "no di" translates to "don't say." The word "mentiras" translates to "lies." Therefore, when combined, the command translates to "don't say lies."

However, the structure of the command is not grammatically correct in Spanish. The correct structure should be "no digas mentiras," where "digas" is the correct conjugation of the verb "decir" (to say) in the informal command form. Therefore, the correct command should be "no digas mentiras" instead of "no di mentiras."
