The following sentence has been divided into parts. One of them contains an error. Select the part that contains the error from the given options.
"Let us, at any rate, / give him / an outline out the case, / and hear what he has to say."

Explanation of the Correct Answer:
· The phrase "an outline out the case" is incorrect because "out" is unnecessary.
· The correct phrase should be "an outline of the case."
· The preposition "of" correctly links "outline" with "case."
Other options:
· (b) "give him" → Correct; grammatically fine.
· (c) "and hear what he has to say." → Correct; no error.
· (d) "Let us, at any rate," → Correct; this phrase correctly conveys an idea of emphasis.
Thus, the correct answer is (a) an outline out the case (should be "an outline of the case").
