English grammar — Spot the error (choose the segment that contains a grammatical error; choose ‘‘No error.’’ if the sentence is correct). Sentence: Our school is making every possible effort to provide best facilities and personal attention for each child.

Introduction / Context:
This question examines article usage with superlatives and preposition choice with “attention.” The sentence aims to speak about the highest standard of facilities provided by the school.

Given Data / Assumptions:

• With superlative adjectives, English normally uses the definite article “the.”
• “Attention” to a person or thing typically takes the preposition “to.”

Concept / Approach:
Identify the superlative structure: “best facilities.” This requires “the best facilities.” Also consider improving “attention for each child” to “attention to each child,” though the test demands selection of one erroneous segment; the most explicit error is the missing article before “best.”

Step-by-Step Solution:

Verification / Alternative check:
Corrected sentence: “Our school is making every possible effort to provide the best facilities and personal attention to each child.”

Why Other Options Are Wrong:

• A/B: Grammatically sound.
• D: While “to” is preferable to “for,” the primary, unambiguous error is in C.

Common Pitfalls:
Omitting “the” before superlatives and using “for” where “to” is idiomatic with “attention.”

Final Answer:
to provide best facilities
