Which metal was earlier called Wolfram?

Tungsten

The correct answer is option 1. Tungsten.

The metal that was earlier called Wolfram is Tungsten.

Tungsten was originally named "wolfram" in English, derived from the Swedish term "volfram," which itself is derived from the earlier name "wolframite," a mineral from which tungsten is extracted. The transition from "wolfram" to "tungsten" occurred in the 18th century, with "tungsten" being derived from the Swedish words "tung" and "sten," meaning "heavy stone," reflecting tungsten's high density.
