Answer:
D working alone
Explanation:
Working alone is the only option that could potentially be a safety hazard; if you have no one watching your back, errors could occur, like dropping glass or burning your hand, and no one is around to help you.
Choices A, B, and C are not correct because those are all good safety standards.
<em>Answer</em><em>:</em><em>2</em><em>7</em><em>%</em><em> </em><em>According</em><em> </em><em>to</em><em> </em><em>the</em><em> </em><em>cylinder</em><em>.</em>
Cs is formed at anode and Sr is formed at cathode.
<h3>What is Oxidation Half reaction ? </h3>
The half reaction of overall reaction in which reactant loses electrons during the reaction is called Oxidation Half Reaction.
<h3>What is reduction Half reaction ? </h3>
The half reaction of overall reaction in which reactants gains its electrons during the reaction is called Reduction half reaction.
At the cathode (-ve electrode), cations are reduced and At the cathode (-ve electrode), anions are oxidized.
Reduction: Sr⁺² + 2e⁻ → Sr
Oxidization: 2Br⁻ (l) → Br₂ (g) + 2e⁻
Thus from the above conclusion we can say that Cs is formed at anode and Sr is formed at cathode.

<h2>Answer : Option A) Arm and leg muscles and option D) Striated or skeletal muscle</h2><h3>Explanation : </h3>
Voluntary muscles are those muscles which are and can be consciously controlled.
These includes biceps, triceps which are the muscles that are present in arms.
The leg muscles are also voluntary muscles, with addition to this the striated or skeletal muscles are also classified as voluntary muscles.
It is seen that most of the skeletal muscles are attached to bones by bundles of collagen fibers known as tendons are controlled voluntarily.
