[tex]$100 \, \text{mL}$[/tex] of engine oil, and [tex]$800 \, \text{mL}$[/tex] of water are placed in a rectangular plastic container. Each container also holds [tex]$f$[/tex] cubes (5 cubic centimeters each) representing animals in the water. Each group is tasked with removing as much oil as possible in a 20-minute period, leaving "clean water" in the container, using whatever tools they brought. The results of the "clean-up" are presented in the table below.

\begin{tabular}{|c|c|c|}
\hline Group & Vegetable oil removed [tex]$(\text{mL})$[/tex] & Engine oil removed [tex]$(\text{mL})$[/tex] \\
\hline 1 & 10 & 0 \\
\hline 2 & 110 & 20 \\
\hline 3 & 60 & 130 \\
\hline 4 & 80 & 40 \\
\hline
\end{tabular}

Based on the results above, which group's data are obviously unreliable?

A. Group 1
B. Group 2
C. Group 3
D. Group 4

Let's analyze the given data to determine which group's data is obviously unreliable.

We have the results in a table format:

[tex]\[ \begin{tabular}{|c|c|c|} \hline Group & Vegetable oil removed (mL) & Engine oil removed (mL) \\ \hline 1 & 10 & \\ \hline 2 & 110 & 20 \\ \hline 3 & 60 & 130 \\ \hline 4 & 80 & 40 \\ \hline \end{tabular} \][/tex]

We notice that Group 1's data is missing the amount of engine oil removed. This makes their data incomplete and therefore unreliable when compared to the data from the other groups, which all provided both vegetable oil and engine oil removal amounts.

Thus, the group whose data is obviously unreliable is:

Group 1
