Correct Answer - Option 2 : Gold

Explanation:

Tensile strength:

Tensile strength is the ability of a material to withstand a pulling (tensile) force and refers to the breaking strength of a material when applying a force capable of breaking many strands of the material simultaneously, at a constant rate of extension/load. It is customarily measured in units of force per cross-sectional area.
Tensile strength is the amount of load or stress that can be handled by a material before it stretches and breaks. As its name implies, tensile strength is the material’s resistance to the tension that is caused by mechanical loads applied to the material. The ability to resist breaking under tensile stress is one of the most important and widely measured properties of materials used for structural applications.
The tensile strength is the maximum tensile stress that a material can be subjected to before failure, although the actual definition of failure usually varies according to the material’s type and design. Reduction in ductility and an increase in brittleness are associated with an accelerated corrosion rate, which in turn can change the failure of the material from a ductile failure to a much more dangerous brittle failure.

There are three types of tensile strength:

Yield strength - The stress a material can withstand without permanent deformation
Ultimate strength - The maximum stress a material can withstand
Breaking strength - The stress coordinate on the stress-strain curve at the point of rupture

Tensile strength is a limit state of tensile stress that leads to tensile failure in one of two manners:

Ductile failure - Yield as the first stage of failure, some hardening in the second stage, and breakage after a possible "neck" formation.
Brittle failure - Suddenly breaking into two or more pieces at a low-stress state.
