I'm pretty sure that significant figures is just the amount of numbers there is. So, in this case I think the answer would be D. 5
The Rutherford experiment proved the Thomson “plum-pudding” model of the atom to be essentially correct did not give the results described and is denoted as option A.
<h3>What is Thomson “plum-pudding” model?</h3>
This model was proposed by J.J Thomson in which referred an atom as a sphere of positive charge, and negatively charged electrons are embedded in it to balance the total positive charge.
This model was incorrect and the Rutherford atomic model was adopted in which he described the electrons orbits about a tiny positive nucleus.
The nucleus contains protons and neutrons instead thereby making it the correct choice.

The options include the following:
a.The Rutherford experiment proved the Thomson “plum-pudding” model of the atom to be essentially correct.
b.The Rutherford experiment was useful in determining the nuclear charge on the atom.
c.Milikan’s oil-drop experiment showed that the charge on any particle was a simple multiple of the charge on the electron.
d.The electric discharge tube proved that electrons have a negative charge
They're both a part of an atom.
The color change of a pH indicator is caused by the dissociation of the H+ ion from the indicator.
<h3 /><h3>What is indicator?</h3>
In science, a marker capability or a trademark capability of a subset An of a set X is a capability characterized from X to the two components set {0, 1}, normally signified as, and it demonstrates whether a component in X has a place with A. Markers are insights used to gauge current circumstances as well as to figure monetary or financial patterns. In the realm of money management, pointers regularly allude to specialized diagram designs getting from the value, volume, or open revenue of a given security. Markers are insights used to gauge current circumstances as well as to conjecture monetary or financial patterns. In the realm of money management, pointers normally allude to specialized graph designs getting from the value, volume, or open revenue of a given security.
