D-neither
Tech A is correct in saying that voltage is electrical pressure but incorrect in saying that resistance is an opposition to electrical power; resistance is actually an opposition to current, not power.
Tech B is correct in that current IS the rate of electrical flow (in couloumbs per second), but is incorrect in his statement about voltage. See above.
