To determine which word cannot be formed using the letters of the word "CONSTRUCTION," we need to examine if each option can be spelled using the available letters. Let's break down the analysis for each option:
- SUCTION:
- Letters: S, U, C, T, I, O, N
- "CONSTRUCTION" contains all these letters.
- COINS:
- Letters: C, O, I, N, S
- "CONSTRUCTION" contains C, O, I, N but doesn't have an S after accounting for its usage in "SUCTION."
- CAUTION:
- Letters: C, A, U, T, I, O, N
- "CONSTRUCTION" contains all these letters.
- NOTION:
- Letters: N, O, T, I, O, N
- "CONSTRUCTION" contains all these letters.
Among the choices, the word COINS cannot be formed as it requires an S, which is already used in forming "SUCTION" without repetition in "CONSTRUCTION."
