Tag the object you want to cause the destruction as ObjectA, and than test for the tag…

Try this out.

function OnTriggerEnter (col : Collider ) {
    if(col.transform.tag == "ObjectA"){    
        Destroy(gameObject);
    }
}

Another variant is : ( if you have obj A,B,C and A C destroy )

function OnTriggerEnter (col : Collider )
{
if (col.gameObject.name == A != col.gameObject.name == C)
{
Destroy(gameObject);
}
}
