In which fishes is there the presence of exceptionally large otolith?

Correct option is D

Sciaenids develop very large sagittal otoliths (ear stones), often proportionally larger than in many other teleost families; linked to their acoustic ecology.
Functional & Research Details
Function: otoliths contribute to balance and hearing; larger otoliths may enhance sensitivity to low-frequency sounds produced by swimbladder drumming.
Practical significance: otoliths used for age and growth studies (increment analysis), stock identification, palaeo-ichthyology.
Species examples: Johnius, Sciaena, Nibea.
Ecological notes
Sciaenids are known for sound production (mating, territorial) — swimbladder muscles vibrate producing drumming sounds.
Notes on other options
Serranidae, Salmonidae, Cyprinidae have otoliths but typically not exceptionally large like sciaenids.
