__Steps 1 & 2: Understand Question and Draw Inferences__

In this question, we are given

- A company produces a certain toy in only 2 sizes, small or large, and in only 2 colors, red or green.
- For each size, there are equal numbers of red and green toys in a certain production lot.

We need to determine

- The fraction of the total number of green toys, which are large.

To determine this, we need to know the total number of green toys, and how many of them are large ones.

Let us assume that

- Number of small red toys produced = S
- Number of large red toys produced = L

As there are equal number of red and green toys produced in each production lot, we can say

- Number of small green toys produced = S
- Number of large green toys produced = L

Therefore, fraction of the total number of green toys, which are large = L / (S+L)

With this understanding, let us now analyse the individual statements.

__Step 3: Analyse Statement 1__

__Step 3: Analyse Statement 1__

As per the information given in statement 1, in the production lot, 400 of the small toys are green.

- Therefore, we can say S = 400.
- However, from this statement, we cannot determine the value of L.

Hence, statement 1 is not sufficient to answer the question.

__Step 4: Analyse Statement 2__

__Step 4: Analyse Statement 2__

As per the information given in statement 2, in the production lot, 2/3 ^{rd} of the toys produced are small.

- Total number of small toys = S + S = 2S
- Total number of large toys = L + L = 2L
- Therefore, we can say = 2S / (2S + 2L) = 2/3
- Or, S/ S+ L = 2/3

- Hence, L/ S + L = 1 – 2/3 = 1/3

As we can determine the value of L/ S+ L, statement 2 is sufficient to answer the question.

__Step 5: Combine Both Statements Together (If Needed)__

__Step 5: Combine Both Statements Together (If Needed)__

Since we can determine the answer from statement 2 individually, this step is not required.

Hence, the correct answer choice is option B.
