Express the Null Hypothesis and the Alternative Hypothesis in Symbolic $( \mu , p , \sigma )$

Express the null hypothesis and the alternative hypothesis in symbolic form. Use the correct symbol $( \mu , p , \sigma )$ for the indicated parameter.
-A researcher claims that the amounts of acetaminophen in a certain brand of cold tablets have a standard deviation different from the $\sigma = 3.3 \mathrm { mg }$ claimed by the manufacturer.

A)
$\begin{array}{l}\mathrm{H}_{0}: \sigma \leq 3.3 \mathrm{mg} \\\mathrm{H}_{1}: \sigma>3.3 \mathrm{mg}\end{array}$

B)
$\begin{array}{l}\mathrm{H}_{0}: \sigma \geq 3.3 \mathrm{mg} \\\mathrm{H}_{1}: \sigma<3.3 \mathrm{mg}\end{array}$

C)
$\begin{array}{l}\mathrm{H}_{0}: \sigma \neq 3.3 \mathrm{mg} \\\mathrm{H}_{1}: \sigma=3.3 \mathrm{mg}\end{array}$

D)
$\begin{array}{l}\mathrm{H}_{0}: \sigma=3.3 \mathrm{mg} \\\mathrm{H}_{1}: \sigma \neq 3.3 \mathrm{mg}\end{array}$
