Option 1: Personification -> Giving human qualities to non-human entities; not applicable here as Swami is already human.
Option 2: Transferred Epithet -> When an adjective is transferred from the noun it logically describes to another; not present in this line.
Option 3: Metaphor -> Comparing Swami's energy to that of a young horse (colt) without using 'like' or 'as', highlighting his youthful vigor and excitement.
Option 4: Symbolism -> Using objects to represent abstract ideas; the colt here is a direct comparison, not a symbol.
Hence, Option 3: Metaphor -> The phrase "with the energy of a colt" creates a metaphorical comparison between Swami's energetic, enthusiastic movement and the spirited, energetic nature of a young horse, effectively conveying his excitement about the cricket match -> correct
