What does 'unduly' indicate?

'Unduly' is an adverb that typically conveys the idea of something being excessive or unwarranted. It implies that there is an overstepping of limits or reasonable boundaries in a particular context. When stating that something is done 'unduly,' it suggests that it exceeds what is considered appropriate or necessary.

For instance, if a situation is described as involving 'undue influence,' it indicates that the level of influence exerted is more than what would be acceptable or normal. This usage illustrates the term's connotation of excessiveness, making it clear why the selected answer is correct.

In contrast, the other choices do not align with the meaning of 'unduly.' 'Insufficiently' suggests a lack or shortage, 'moderately' indicates a balanced or average amount, and 'occasionally' refers to something happening from time to time, none of which reflect the excessive nature implied by 'unduly.'
