(F)
![12.](https://img.qammunity.org/2019/formulas/mathematics/high-school/rslddtxlh4mu6gtbaro8fpvz50lbhjaxlk.png)
Step-by-step explanation: We are given to select all the constants in the following expression :
![E=12+x-3.7-8y+(1)/(3)~~~~~~~~~~~~~~~~~~~~~~~~~(i)](https://img.qammunity.org/2019/formulas/mathematics/high-school/ph3fxi3n61bs16zj0aqy65yixs67895lbz.png)
We know that
in an algebraic expression, the constants are those terms which are not multiplied to some unknown variables.
In the given expression (i), there are two unknown variables x and y.
So, the terms which are not multiplied by x or y are the constants in the expression.
Therefore, the required constants are
![12,~~-3.7,~~(1)/(3).](https://img.qammunity.org/2019/formulas/mathematics/high-school/y6jdmh7u5rsnuqrdg0fo689twhna8vssvr.png)
Thus, (B), (C) and (F) are the correct options.
