A) was
B) Till
C) Until
D) since
🧠 Explanation:
The sentence “I cannot come to see you until tomorrow” uses “until” to indicate a time boundary, meaning the action (coming) is delayed until the specified time. Correct preposition use ensures temporal clarity, vital for effective communication. “Until” is appropriate for future-oriented restrictions, unlike “by” or “since.” Mastering prepositions enhances precision in writing or speech, applicable in scheduling, planning, or casual conversations. This usage ensures clear expression of time constraints, crucial for coordinating events or commitments in academic, professional, or personal contexts where timing is essential.
