Select the correct option that is related to the third term in the same way as the second term is related to the first term.

Television : Telecast :: Radio : ?

The correct option is Broadcast.

To solve this analogy, we need to determine the relationship between the first pair of words and apply the exact same logic to the second pair.

Step 1: Analyze the first pair (Television : Telecast)
A Television is a medium or device used to transmit visual images and sound. The process of transmitting these programs over the television medium is called a Telecast. Therefore, the relationship is: Medium : Method of Transmission.

Step 2: Apply the relationship to the second pair (Radio : ?)
A Radio is an audio medium. Following the same logic, the method of transmitting programs over the radio medium is called a Broadcast.

Thus, just as a television telecasts programs, a radio broadcasts programs, making Broadcast the correct corresponding term.
