Explanation:
not understood your point
The given option that has molecules that are solid at room temperature is; D: Saturated Fats
<h3>Molecules at room temperature </h3>
Fatty acids are organic compounds that are poorly soluble in water but soluble in organic solvents.
The two main types of fatty acids are Saturated fatty acids and Unsaturated fatty acid.
Saturated fatty acids contains no double bond in their carbon chains and as such they are solids at room temperature.
Meanwhile, Unsaturated fatty acids contains double bonds in their carbon chains and are thus liquids at room temperature.
The missing options are;
A) Both saturated and unsaturated fats
B) Cholesterol
C) Saturated fats
D) Unsaturated fats

Answer is A
Explanation :
The justification of the third step in her proof of the property of logarithms is; 
; Power rule of exponents
<h3>What are properties of Logarithms?</h3>
From the full question, the second step stopped at;
Now, according to Power Rule for Exponents we know that (a^m)ⁿ = a^(m*n). That means that to raise a number with an exponent to a power, we will multiply the exponent times the power.
Thus, will give us using power rule of exponents
