Each of the following items contains a set of sentences. Identify and select the sentence that has a grammatical or contextual error. If none of the sentences contain any error, select the "all are correct" option.

The sentence that contains a grammatical error is:
"Veteran cricket commentator Harsha Bhogle has been speaking openly for the very first time for his controversial removal from the commentary panel during the IPL."

Detailed Analysis of the Error:

1. Incorrect Preposition Usage:
In this sentence, the preposition "for" is used incorrectly following the phrase "speaking openly for the very first time". When referring to a topic, event, or subject matter that someone is discussing, the appropriate preposition to use is "about" (or "on").

2. Contextual Distortion:
Using "for" distorts the meaning of the sentence. Saying someone is "speaking for his removal" implies advocating in favor of or supporting their own removal. The intended contextual meaning is that Harsha Bhogle is sharing his thoughts regarding the event of his removal. Thus, "for" must be replaced with "about".

3. Corrected Sentence:
"Veteran cricket commentator Harsha Bhogle has been speaking openly for the very first time about his controversial removal from the commentary panel during the IPL."

4. Review of Other Options:
• "The auditor challenged the figures presented in the financial statement and maintained that the projections were inaccurate." — This sentence is grammatically correct and contextually clear.
• "The petition demanding restoration of the original boundary was dismissed by a Division Bench of the High Court." — This sentence correctly utilizes legal terminology and proper sentence structure.
• "German automaker Volkswagen unveiled the ID.7, an advanced electric variant of its flagship sedan lineup." — This sentence is error-free in terms of grammar, tense, and vocabulary.
