I think the correct answer from the choices listed above is option D. The element that behaves most like magnesium would be strontium. It behaves most like magnesium because it is in the same family, the alkaline earth metals. Hope this answers the question.

Explanation

In periodic table, the elements have almost same properties are present in the same group. As Mg and Sr are present in group II-A, so both behave most likely to each other due to having same valence shell electrons as well.
Si and Sn are present in group IV-A which have same behavior but different one from Mg due to different groups.
S is present in group VI-A which show different properties from all others one especially from Mg.

Arrange the following units in decreasing order: nm,km,pm,Dm,mm,m,cm,hm,gm

goblinko [34]

The units are nm (nano-meter), km (kilo-meter), pm (pico-meter), dm (decimeter), mm (millimeter), m (meter), cm (centimeter), hm (hectometer) and gm (gigameter). Now we can express each of these units in terms of m.

1 nm = $10^{-9}m$ , 1 Km = $10^{3}m$ 1 pm = $10^{-12}m$ , 1 dm = 0.1 m, 1 mm = 0.001 m, 1 cm = 0.01 m, 1 hm = 100 m, 1 gm = $10^{9} m$ . Thus the decreasing unit will be
