Assertion(A) : Glucose gives a reddish-brown precipitate with Fehling’s solution
Reason(R)  : Reaction of glucose with Fehling’s solution gives CuO and gluconic acid 

The reducing  group of glucose (-CHO) is oxidized by the $c{u}^{+2}$ ions  in Fehling’s reagent to $c{u}^{+}$ (red copper oxide). Red solution is produced due to formation of cuprous oxide $C{u}_{2}O$ is produced instead of CuO.
