detect electric fields
A
nociceptors
B
electroreceptors
C
megnetoreceptors
Explanation: 

Detailed explanation-1: -electroreception, the ability to detect weak naturally occurring electrostatic fields in the environment. Electroreception is found in a number of vertebrate species, including the members of two distinct lineages of teleosts (a group of ray-finned fishes) and monotremes (egg-laying mammals).

Detailed explanation-2: -Ampullae of Lorenzini (singular Ampulla) are electroreceptors, sense organs able to detect electric fields.

Detailed explanation-3: -In both sea creatures, networks of organs, called ampullae of Lorenzini, constantly survey the electric fields they swim through. Electricity enters the organs through pores that surround the animals’ mouths and form intricate patterns on the bottom of their snouts.

Detailed explanation-4: -Voltage differences across the membrane lining each ampulla then cause nerves to be activated, sending signals to the brain. Electroreceptors are most often used to capture prey, by the detection of electrical fields generated by the prey. For example, this allows sharks to find prey hidden in the sand.

Detailed explanation-5: -Many marine animals, from tiny clams to big fish, produce electric signals. Sharks and other ocean predators, including skates and rays, sense those electric fields. They do it using organs known as ampullae (AM-puh-lay) of Lorenzini. Scientists call such tissues electroreceptors because they detect electric fields.
