Error Spotting – Identify the part of the sentence that contains a grammatical error (choose exactly one; select “No error” if the sentence is fully correct). Sentence: A) He being the eldest son, B) his father expects him C) to take care of several things D) besides his regular studies.

Introduction:
In this error-spotting question, the core issue is a misrelated (dangling) participial phrase. The opening phrase should modify the grammatical subject of the main clause. When that alignment fails, the sentence sounds illogical or ungrammatical.

Given Data / Assumptions:

• The sentence is split into parts A–D; option E means the sentence has no error.
• Part A: "He being the eldest son," introduces a participial/absolute phrase.
• The main clause in B–D has the subject "his father."
• Intended meaning: Because he is the eldest son, expectations are placed on him.

Concept / Approach:
Participial or absolute phrases at the beginning should logically refer to the subject of the main clause. If the main clause begins with a different subject, the modifier becomes misrelated. Prefer: "Being the eldest son, he is expected to..." or use an absolute phrase with proper punctuation and structure.

Step-by-Step Solution:
1) Identify the introductory modifier: "He being the eldest son," (A).2) Identify the main-clause subject: "his father" (B).3) Check logical reference: the introductory phrase should modify the main subject, but it refers to "he," not "his father."4) This mismatch creates a misrelated modifier; therefore the error lies in A.5) A corrected version: "Being the eldest son, he is expected by his father to take care of several things besides his regular studies."

Verification / Alternative check:
If we move "he" to be the subject of the main clause, the sentence reads logically. Keeping "his father" as subject while "he" appears in the opener is ill-formed.

Why Other Options Are Wrong:

• B: Grammatically fine as part of the corrected structure.
• C: Infinitive phrase is standard and correct.
• D: Prepositional phrase "besides his regular studies" is idiomatic.

Common Pitfalls:
Confusing absolute constructions with participial modifiers; assuming any opener with "being" is correct. Ensure the opener logically modifies the subject that immediately follows.

Final Answer:
Option A
