Answer 1

A. All organisms are made up of cells

Answer 2

All organisms are made up of cells

Explanation: (B) is not correct because there are prokaryotes which are unicellular organisms. (C) is not correct because us, humans, can not make our own food. Only plants can do that - hence they are called autotrophs.
