The correct options are
A Under an isolated tree
B Under an umbrella with a metallic end
D In a open garage
When lightning is occurring, a bus or car is a safe place. One should never take shelter under an isolated tree since it may attract lightning. Also, an umbrella with a metallic end may accumulate charge; hence, shelter under it is risky as well. Open garages, storage shades, metal shades are also not safe during lightning.
