correct option : 1 

The English rule against perpetuities is primarily concerned with interests in property that are to arise in the future. The rule aims to prevent the creation of interests that may last indefinitely or beyond a certain period. Under the rule, a future interest in property must vest, if at all, within 21 years after the death of a life in being at the time of the creation of the interest. This ensures that property is not tied up with uncertain future interests for an unreasonable length of time, thus addressing future interests (Option 1).
