Correct Answer:

Solution : According to the question figure –
1. In the given series, the ovals follow a logic of (–2, +1), so for every consecutive figure, two ovals are reduced, then one oval is added, and so on.
2. The diamonds follow a logic of (+2, –1). So, for every consecutive figure, two squares are increased one square is decreased, and so on.
So, following the above pattern, the required figure will be as follows –

Therefore, the complete figure is as follows –

Hence, the third option is correct.
