Select the correct sentence structure from the given four choices.

Answer: There will not be enough time.

Why this is correct:

• Structure uses the expletive 'there' (dummy subject) followed by auxiliary + negation + main verb + complement.

• Correct order: there + will + not + be + enough time.

• Acceptable alternative with contraction: 'There won't be enough time.'

Why the other sentences are incorrect or odd:

• "Will not be enough time there." — Incorrect word order: the auxiliary comes first and 'there' is misplaced at the end. Use the standard form given above.

• "There not will be enough time." — Incorrect placement of 'not'. Negation should follow the auxiliary ('will not'), not precede it.

• "Enough time will there not be." — This inverted form is archaic or used for strong emphasis in poetic or formal contexts; it is not the normal neutral statement order.

Summary: Use 'There will not be enough time.' (or 'There won't be enough time.') for a clear, neutral future-negative statement.
