To solve this problem, we need to understand the rules for writing scientific names according to the binomial nomenclature system.$\newline$This system was developed by Carolus Linnaeus and is used to universally identify species.$\newline$The rules for writing scientific names are as follows:$\newline$• The scientific name is composed of two parts: the genus name and the species name.$\newline$• The genus name is always capitalized, while the species name is not.$\newline$• Both names are italicized or underlined if handwritten.$\newline$• The author's name, who first described the species, is often abbreviated and written after the species name.$\newline$In this case, the scientific name of Mango is $\textit{Mangifera indica}. \newline$• The genus name is $\textit{Mangifera}$ (capitalized and italicized).$\newline$• The species name is $\textit{indica}$ (not capitalized and italicized).$\newline$• The author's abbreviation, $$Linn.$$, is added after the species name.$\newline$Analyzing the options:$\newline$• Option 1: $\textit{Mangifera indica Car. Linn.}$ (Incorrect, as it includes an incorrect author abbreviation.)$\newline$• Option 2: $\textit{Mangifera indica Linn.}$ (Correct, as it follows the rules of binomial nomenclature.)$\newline$• Option 3: $\textit{Mangifera indica}$ (Incomplete, as it lacks the author's name.)$\newline$• Option 4: $\textit{Mangifera Indica}$ (Incorrect, as the species name is capitalized.)$\newline$Therefore, the correctly written scientific name of Mango is Option 2: $\textit{Mangifera indica Linn.}$
