Identify the part (A–E) that contains a grammatical error in the sentence below. If there is no error, choose option E (No error). Sentence (split into parts): A) Rosy herself wash B) all the clothes and C) never gives them D) to the laundry.

Introduction:
This error-spotting item tests subject–verb agreement in simple present tense, as well as the correct placement of an emphatic reflexive pronoun such as "herself".

Given Data / Assumptions:

• Subject: "Rosy" (third-person singular).
• Verb phrase in A: "herself wash".
• Coordinated predicate continues in parts B–D to complete the meaning.
• Standard rule: third-person singular in simple present takes the base verb + s/es.

Concept / Approach:
In simple present, third-person singular subjects require an –s form ("washes"). The reflexive "herself" is acceptable for emphasis ("Rosy herself washes…") but does not change agreement requirements. Therefore, the error lies in part A, where "wash" should be "washes".

Step-by-Step Solution:
1) Identify subject: "Rosy" → third-person singular.2) Apply agreement rule: use "washes" not "wash".3) Keep emphasis: "Rosy herself washes…".4) Check remaining parts: "never gives them to the laundry" is grammatical and idiomatic.

Verification / Alternative check:
Paraphrase: "Rosy herself washes all the clothes and never gives them to the laundry." This reads naturally and follows agreement rules.

Why Other Options Are Wrong:
B: Correct object phrase introducing "all the clothes".C: "never gives them" agrees with an implied subject and is idiomatic.D: "to the laundry" is a correct prepositional complement.

Common Pitfalls:
Learners may think the emphatic "herself" licenses base-form verbs. It does not; agreement rules remain unchanged.

Final Answer:
A (Write: "Rosy herself washes")
