Given a short query with keyphrases about a research idea in 2016 in the domain of artificial intelligence, recommend the relevant datasets to validate the research idea from options provided. A short description of the datasets is also provided to help you.

Query: A simple, yet robust, 2-D convolutional neural network extended to a concatenated 3-

Keyphrases: video classification

Dataset description:
ObjectNet: ObjectNet is a test set of images collected directly using crowd-sourcing. ObjectNet is unique as the objects are captured at unusual poses in cluttered, natural scenes, which can severely degrade recognition performance.
UCF101: UCF101 dataset is an extension of UCF50 and consists of 13,320 video clips, which are classified into 101 categories. These 101 categories can be classified into 5 types (Body motion, Human-human interactions, Human-object interactions, Playing musical instruments and Sports).
ImageNet-A: The ImageNet-A dataset consists of real-world, unmodified, and naturally occurring examples that are misclassified by ResNet models.
SI-SCORE: A synthetic dataset uses for a systematic analysis across common factors of variation.

Options:- A: ObjectNet  B: UCF101  C: ImageNet-A  D: SI-SCORE
