Correct answer
Explanation
'Apt to' is a phrase that means 'having a tendency to' or 'likely to'. When you say something is 'apt to leak', you mean it has a tendency or inclination to leak - it's likely to happen. This is similar to saying 'prone to leak'. 'Amiss' means wrong or out of place, 'ample' means plentiful, 'apparent' means obvious, and 'appalled' means shocked - none of which fit this grammatical structure or meaning.
