Problem

A mass of

8.26\,\text{g}\,\pm\,0.03\,\text{g}

is reduced by

2.13\,\text{g}\,\pm\,0.02\,\text{g}

. The correct result, expressed with its absolute uncertainty, is a)

6.13\,\text{g}\,\pm\,0.04\,\text{g}

6.1\,\text{g}\,\pm\,0.05\,\text{g}

6.13\,\text{g}\,\pm\,0.05\,\text{g}

6.13\,\text{g}\,\pm\,0.03\,\text{g}
