(i) the marriage was solemnized, or
(ii) the respondent, at the time of the presentation of the petition, resides, or
(iii) the parties to the marriage last resided together, or
(iv) the petitioner is residing at the time of the presentation of the petition, in a case where the respondent is, at that time, residing outside the territories to which this Act extends, or has not been heard of as being alive for a period of seven years or more by those persons who would naturally have heard of him if he were alive.]
