As per Indian Protocol, who among the following ranks highest in the order of precedence?

The official Table of Precedence places Governors of States within their respective States at a higher article number (Article 4) than Former Presidents (Article 5) and the Deputy Prime Minister (Article 5A), making a Governor in his state senior to those dignitaries [2]. The Speaker of the Lok Sabha is placed with the Chief Justice of India at a lower ranking than the Governor and is positioned below the Former Presidents/Deputy Prime Minister in the precedence order as noted in authoritative protocol summaries [2]. Therefore, among the given options, a Governor of a State within his State ranks highest in the Indian order of precedence.
