Explain what happens when you use the OrElse operator.

Match each item with a statement below. a.ControlChars.NewLine constant f.AndAlso b.condition g.& c.> h.single-alternative selection structure d.dual-alternative selection structure i.OrElse e.< -Contains two sets of instructions: one set is processed when the condition is true and the other set is processed when the condition is false.
