What is the purpose of PROC CDISC in relation to CDISC ODM files?

PROC CDISC is specifically designed to facilitate working with CDISC Operational Data Model (ODM) files, which are crucial for the interchange of data in clinical trials. The primary function of this procedure is to read and process CDISC ODM data, and it is essential that it supports the data up to version 1.2. This ability to read and interpret the structure and contents of ODM files allows researchers and statisticians to effectively utilize the data for further analysis, reporting, and compliance with regulatory standards.

In the context of clinical trials, understanding how to read and manipulate the data structured in ODM format is fundamental for ensuring that the data can be accurately analyzed and reported. Hence, the purpose of PROC CDISC aligns directly with the need to interact with CDISC ODM files, making option B the correct choice.
