Answer 1

The correct option is D $\begin{array}{cc}\text{Sympathetic system}& \text{Parasympathetic system}\\ \text{1) Trachea dilates}& \text{3) Glucose is converted to glycogen}\\ \text{2) Heart beat increases}& \text{5) The pupils constrict}\\ \text{4) Production of hormones increases}& \text{6) Urinary bladder contracts}\end{array}$

When facing emergency, sympathetic nervous system prepares us for a 'fight or flight' response. It increases our heart beat, slows down digestion, dilates our pupils and also converts glycogen into glucose. When the danger is subsided, the parasympathetic system decreases our heart beat, constricts pupils, digestion becomes normal and glucose is converted into glycogen to bring back the body to a relaxed state.
