Iron & Nickel. There are also small doses of other unimportant garbage.
C is your answer. (Iron & Nickel)
Answer:
Wooden poles are rigid. That means that if you apply a force on the top of it, energy will travel directly to the ground (and you will just feel a very strong normal force) and the pole won't store any energy. An elastic pole will flex, storing energy that won't go directly to the ground, but as it recovers it's original shape, half of this stored potential energy will transforme to kinetic energy for the athlete, giving them energy to jump higher.

Explanation:
CASE: A wire is moved through the field of a magnet
As the wire is moved through the field of a magnetic the magnetic flux through the circuit loop changes,; therefore current is induced.
CASE: A magnet is held close to a wire
There needs to be relative motion between the wire and the magnet for the current to be induced; therefore, simply holding a magnet close to a wire will not induce current in the circuit.
CASE: A magnet is moved into a coil of wire
As the magnet is moved into a coil of wire, the magnetic flux through the coil changes, and therefore, the current is induced.
CASE: A magnet is moved out of coil of wire
Moving a magnet out of coil of wire also changes the magnetic flux through the coil; therefore, the current is induced.
CASE: A magnet rests in coil of wire
There needs to be relative motion between the coil of wire and the magnet for the current to be induced; therefore, a magnet resting in the coil of wire will no induce any current in the coil.
