Muscle tissue
Explanation: Muscle tissue is a soft tissue that makes up most of the tissues in the muscles of the human muscular system. It is the only type of tissue that has cells with the ability to contract. Skeletal muscle tissue is attached to bones by tendons.
Answer : The correct answer is, Halide hydrocarbon.
Explanation :
Freon : Freon are the simple aliphatic organic compounds which may contains fluorine, carbon, hydrogen, chlorine or bromine. So, they are a type of chlorofluoro carbons (CFCs).
They are considered as refrigerants which are used in air-conditioning and refrigeration system.
We can use the reactivity series of metals to solve this.
The reactivity series of metals are (in descending order) :
Potassium, sodium, Lithium, calcium, Magnesium, aluminum, zinc, iron, tin, lead, copper, mercury, silver, platinum, gold.
Since Potassium is the most reactive, the reaction with water should produce extremely violent gas.
Sodium is the next most reactive, so it should produce violent gas.
And Lithium is the least reactive out of the 3 metals, so it should be strong gas formation.
In addition, the gas produced should be hydrogen, since the reaction of metals should water should produce "metal name" hydroxide + hydrogen.
