Explanation:

Step1: Define an equation

An equation is a mathematical statement that two expressions are equal, containing an equals sign ($=$).

Step2: Analyze Option A

$3b = 5$ has an equals sign, so it is an equation.

Step3: Analyze Option B

$43(4x + 7y)$ has no equals sign, it is just a single algebraic expression.

Step4: Analyze Option C

$78 = 3p - 37$ has an equals sign, so it is an equation.

Step5: Analyze Option D

$a - 17 = 1,825,026$ has an equals sign, so it is an equation.
