Choose the wrong statements with respect to distinguishing characteristics of living beings

1 In majority of higher, the growth and reproduction are mutually exclusive events

3 Isolated metabolic relations in-vitro are neither living things nor living reactions

4 Growth cannot be taken as a defining property of living organisms if we take increase in body mass as a criterion on growth
