Neigh : Bray : Bark — Select the option that belongs to the same category of characteristic animal vocalizations as the given trio.

Introduction / Context:
'Neigh', 'bray', and 'bark' are words naming typical animal sounds (horse, donkey, dog respectively). The question asks you to choose a word from the options that fits the same 'animal vocalization' class.

Given Data / Assumptions:

• The trio are verbs/nouns denoting animal sounds.
• Options include unrelated terms and one sound verb.
• Minor spelling normalization is allowed by recovery policy when intent is clear.

Concept / Approach:
Among the options, 'Gibber' is a verb meaning to talk rapidly and unintelligibly; in common lists it appears as an onomatopoeic vocalization word (often used for apes/monkeys in older texts). 'Peseta' is a former Spanish currency; 'Majlis' is an Arabic word for council/assembly; 'Leaf' is a plant part. Thus only 'Gibber' belongs to a vocalization/sound class akin to 'neigh', 'bray', 'bark'.

Step-by-Step Solution:
1) Identify the shared class: animal/creature vocalization words.2) Screen options: only a sound-related verb should qualify.3) 'Gibber' matches sound/vocalization usage; others are unrelated.4) Select 'Gibber'.

Verification / Alternative check:
Checking each given: neigh (horse), bray (donkey), bark (dog). 'Gibber' fits the lexical field of vocal sounds; other options are clearly non-sound entities.

Why Other Options Are Wrong:

• Peseta: Currency; wrong category.
• Majlis: Council/assembly; wrong category.
• Leaf: Plant organ; wrong category.
• None of these: Incorrect because 'Gibber' fits.

Common Pitfalls:
Overthinking because 'gibber' is less common in animal-sound lists; however, it is the only sound-related choice present.

Final Answer:
Gibber
