"Out" combines with several words to form valid English verbs. "Outshine" means to be more impressive or brilliant than someone else. "Outnumber" means to exceed in number or count. "Outrun" means to run faster than someone or something, or more broadly to outpace.
"Outbug" is not a recognised English word. "Bug" does not combine with "out" to form any standard term used in English.
Since Shine, Number, and Run all form genuine words with "Out", while Bug does not, the word that cannot be coupled with "Out" is Bug, making option 3 the correct answer.
