Final answer:
The word 'planned' is the antonym of 'random,' indicating a deliberate intention behind an action, in contrast to something done without method.
Step-by-step explanation:
The antonym of random is planned. 'Random' means something that is done without method or conscious decision, whereas 'planned' implies that there is a deliberate intention or design behind the action. The other options, such as 'surprising', 'scattered', and 'ironic' do not represent the opposite of 'random'. 'Surprising' relates to the unexpectedness of an event, 'scattered' implies being spread or dispersed irregularly, and 'ironic' indicates a situation where the outcome is contrary to what was expected. Therefore, within the context of this question, 'planned' serves as the correct antonym for 'random'.
An antonym of random is planned. Random means happening without a definite plan or pattern, while planned means carefully thought out and organized. For example, if you randomly pick a number, you might choose any number without a specific order. On the other hand, if you planned to pick a number, you would have a specific number in mind and a reason for choosing it.
