Using your knowledge of hominid evolution, which of the following correctly associates the given brain capacities with the hominid species in the table in order from smallest to largest?

\begin{tabular}{|l|l|l|}
\hline
Species & Time period (millions of years ago) & Tool use \\
\hline
A. afarensis & [tex]$3.6-2.8$[/tex] & Possible tool use \\
\hline
A. africanus & [tex]$3.0-2.4$[/tex] & Possible tool use \\
\hline
H. habilis & [tex]$2-1.5$[/tex] & Simple stone tools \\
\hline
H. neanderthalensis & [tex]$0.13-0.035$[/tex] & Complex stone tools \\
\hline
\end{tabular}

A. A. afarensis, A. africanus, H. habilis, H. neanderthalensis

B. H. habilis, A. afarensis, A. africanus, H. neanderthalensis

C. A. afarensis, H. neanderthalensis, H. habilis, A. africanus

D. H. neanderthalensis, H. habilis, A. africanus, A. afarensis

To determine the correct association of brain capacities with hominid species in order from smallest to largest, we need to analyze the evolutionary progression and characteristics stated in the table regarding these hominid species:

1. A. afarensis:
- Time period: 3.6-2.8 million years ago
- Tool use: Possible tool use
- Characteristics: One of the earliest hominids and expected to have the smallest brain capacity among the mentioned species.

2. A. africanus:
- Time period: 3.0-2.4 million years ago
- Tool use: Possible tool use
- Characteristics: Slightly more evolved than A. afarensis, thereby expected to have a slightly larger brain capacity.

3. H. habilis:
- Time period: 2-1.5 million years ago
- Tool use: Simple stone tools
- Characteristics: Known as "handy man", has a more advanced brain capacity due to tool usage.

4. H. neanderthalensis:
- Time period: 0.13-0.035 million years ago
- Tool use: Complex stone tools
- Characteristics: Most advanced in tool use, expected to have the largest brain capacity among the specified species.

Given this evolutionary sequence and characteristics, the correct order from smallest to largest brain capacity is:

- A. afarensis
- A. africanus
- H. habilis
- H. neanderthalensis

Therefore, the correct answer is:
1. A. afarensis, A. africanus, H. habilis, H. neanderthalensis
