The IBM Cloud services that can help in building a solution for collecting, transforming, and analyzing data from different formats areEvent Streams and App Connect.

IBM Event Streams: This is an Apache Kafka-based messaging service designed to handle real-time data streaming and ingestion. It can collect and distribute data from various sources, making it suitable for scenarios involving data from multiple sources or formats.

IBM App Connect: App Connect provides integration capabilities that allow for data transformation, mapping, and filtration, enabling the unification of data formats before processing. It helps in creating rules to transform data according to the desired structure.

References from IBM Cloud Professional Architect Materials:

IBM documentation on Event Streams and App Connect describes how these services can work together to handle and transform data from multiple sources for real-time analytics and integration.

Other options are incorrect:

A. API Connect and Asperafocus on API management and high-speed data transfer, respectively.

C. Event Streams and Asperaare not geared towards data transformation and integration.

D. App Connect and Datastaxdo not provide the necessary data streaming and collection capabilities.
