Help meee!! PLZ It's worth 20 points and if you get it right I will mark brainlist.

I Think it should be Mixture.

Explanation: Because titanium is a mixture and its only 1% of the 2nd option and its not a pure substance and it might be a compound.

the order for strong to weak forces such as

strong nuclear force → electromegnetic force → weak nuclear force → gravitational force

the fundamental forces are those forces that act between to objects or element to make interactions. there are four types of fundamental forces such as strong and weak nuclear forces (due to protons and electrons), electromagnetic force (due to the motion of electrons) and gravitational force (due to orbital movement of the planet). if these forces are arranged on the basis of their maximum strength then the order is

strong nuclear force → electromegnetic force → weak nuclear force → gravitational force

there are no contact forces mentioned on the list of choices that you've provided.
