Step 1: Classification of Sentences:
Sentences are grammatically categorized into four major types based on their purpose:
• Declarative: Makes a statement or states a fact (e.g., “The sun rises in the east.”).
• Interrogative: Asks a question and ends with a question mark (e.g., “Where are you going?”).
• Imperative: Gives a direct command, order, request, or advice (e.g., “Please sit down.”).
• Exclamatory: Expresses strong, sudden emotion and ends with an exclamation mark (e.g., “What a beautiful day!”).
Step 2: Analyzing the Given Sentence:
The sentence “Come with us right now.” contains an instruction to perform an action immediately. There is no explicit grammatical subject; instead, the subject is the implied second-person pronoun “you” (i.e., “[You] Come with us right now.”). This structural pattern is the defining hallmark of a command.
Step 3: Evaluating the Options:
Option (A) is incorrect as there is no question mark or interrogative structure. Option (B) is incorrect because it is not a statement of fact or opinion. Option (D) is incorrect because, although emphatic, it is structured as a command rather than an exclamatory phrase (which typically begins with “how” or “what”). Therefore, option (C) is the only correct classification.
