Zoological name of tiger is

The correct answer is Panthera tigris.

To understand why this is the correct biological (zoological) name, let us break down the binomial nomenclature of the tiger:
1. Binomial Nomenclature: Every organism is given a scientific name consisting of two parts: the Genus name (capitalized) and the specific epithet (lowercase). Both names are italicized or underlined.
2. Genus: The tiger belongs to the genus Panthera, which includes other big cats such as lions (Panthera leo), leopards (Panthera pardus), and jaguars (Panthera onca).
3. Species: The specific epithet for the tiger is tigris. Therefore, the complete zoological name is Panthera tigris.

Let's also identify the other options to understand why they are incorrect:
- Mangifera indica is the botanical name of the mango tree.
- Solanum tuberosum is the botanical name of the potato.
- Solanum melongena is the botanical name of the eggplant (brinjal).
