In the following question, a sentence is given in Direct speech. Choose the option that best expresses the same idea in Indirect or reported speech. The guide suggested, "Let us rest here for a while."

Introduction / Context:
This question involves reporting a suggestion expressed with the construction "Let us". The guide is proposing a short rest to the group at a particular place. In standard grammar for competitive exams, such sentences are reported using patterns like "suggested that we should" or "suggested that we" plus base verb. The task is to choose the alternative that most completely and accurately reflects the original message.

Given Data / Assumptions:

• Direct speech: The guide suggested, "Let us rest here for a while."
• The speaker is the guide, and "us" includes the guide and the group members.
• The verb "suggested" already appears in the reporting part.
• The group is at a particular location, indicated by "here".
• The time phrase "for a while" indicates a short period of resting.

Concept / Approach:
The construction "Let us" in Direct speech is usually converted into "suggested that we should" or "proposed that we should" in Indirect speech. The place word "here" normally becomes "there" when the sentence is reported from a different location. The time phrase "for a while" is kept because it accurately reflects the duration of the rest. While modern English can use "suggested that we rest", many exam patterns still prefer "that we should rest" as a very clear expression of suggestion.

Step-by-Step Solution:

Verification / Alternative check:
The final sentence clearly expresses a suggestion made by the guide to the group, includes both place and duration, and uses an accepted exam style pattern. The pronoun "we" shows that the guide includes himself with the others, which is true of "Let us". The change of "here" to "there" is grammatically correct in reported speech because the point of reference has shifted.

Why Other Options Are Wrong:
Option B says "that we rest there" and omits "for a while", so it loses some information from the original sentence. Option C leaves out "there" and only mentions "rest for a while", which drops the location. Option D uses a gerund phrase "resting for a while there", which is grammatical but again does not clearly show the inclusive sense of "Let us" and is less standard in exam patterns. Option A is the only one that preserves all key details: the group action, the specific place, and the short duration.

Common Pitfalls:
Learners sometimes forget to change "here" to "there" in reported speech or they do not preserve all parts of the original suggestion. Another frequent error is treating "Let us" as a command and using "ordered" instead of "suggested" with "to" plus infinitive, which changes the tone. Recognising "Let us" as a suggestion rather than a strict order is essential for selecting the correct reporting structure.

Final Answer:
The correct reported speech sentence is The guide suggested that we should rest there for a while.
