To find the instantaneous velocity of the object at $t = 1$, we need to use the definition of the derivative, which gives us the instantaneous rate of change of the position function $s(t)$. The formula for the instantaneous velocity at a given time $t = a$ is:

$v(a) = \lim_{h \to 0} \frac{s(a+h) - s(a)}{h}$

This corresponds to option C in the multiple-choice list.

To find the instantaneous velocity at $t = 1$, we need to differentiate the given position function $s(t) = 4t^2 + 3t + 4$ and then evaluate the derivative at $t = 1$.

First, let's differentiate $s(t)$:

$s(t) = 4t^2 + 3t + 4$

Using the power rule for differentiation, we get:

$s'(t) = \frac{d}{dt}(4t^2) + \frac{d}{dt}(3t) + \frac{d}{dt}(4)$ $s'(t) = 8t + 3$

Now, we substitute $t = 1$ into the derivative:

$s'(1) = 8(1) + 3$ $s'(1) = 8 + 3$ $s'(1) = 11$

Therefore, the instantaneous velocity at $t = 1$ is $11$.
