Which metal is described as bluish white, soft, and ductile?

The metal that is bluish white, soft, and ductile is lead. Lead is known for its distinctive bluish-white color when freshly cut, and its physical properties include being soft and highly ductile, which means it can be easily shaped and formed without breaking. This ductility is a key characteristic that allows lead to be utilized in applications requiring malleability, such as in lead sheets or soldering materials.

In contrast, other metals in the options do not possess the same combination of properties. Tin, while also soft and ductile, has a lighter color and is not typically described as bluish white. Aluminum is a lighter-colored, more robust metal known for its strength-to-weight ratio, but does not share the same softness as lead. Copper, characterized by its reddish-brown color, is also not bluish white and, while it is ductile, it does not share the same softness associated with lead. This characterizes lead distinctly in the context of this question regarding its color and mechanical properties.
