B. Iron nail
C. Thin iron plate
D. Solid iron cube​

Answer 1

Answer:

iron fillings

hope it will help u

Answer 2

Iron fillings would rust the fastest. (Option A)

• The completion time of the rusting process on the iron surface depends on various factors and the surface area of the iron is one of those factors.

• The surface area is inversely proportional with the completion time of the rusting process.

• Which means,the iron objects which have less surface area will rust at more faster speed.

• And, among the substances mentioned in the question,the iron filling has the less amount of surface area as it is made out of very fine iron dust.

• So,the iron fillings will complete rusting process at a faster speed.
