The lookup case_sensitive_match option is specified in the transforms.conf file. This configuration file is responsible for defining data transformations, including how lookups are configured and processed. Modifying this option within transforms.conf allows administrators to set whether or not lookups should be case-sensitive when matching keys.

The props.conf file is primarily used for defining source type characteristics and specifying how data is processed at index time or at search time, but it does not directly deal with lookup configuration options.

The inputs.conf file is used for managing data input configurations, and the outputs.conf file pertains to data output settings. Neither of these files has functionalities related to lookups, making them unsuitable for adjusting the case sensitivity of lookups.

Thus, the transforms.conf file is the correct choice as it directly controls the behavior of lookups, including the case sensitivity setting.
