Multiple Query Trace Flags

I want to enable two trace flags, 4199 and 4137, for a single query. How should I do this:

-- A
SELECT
  a.AddressID
, a.AddressLine1
, a.AddressLine2
, a.City
, a.StateProvinceID
, a.PostalCode
, p.FirstName
, p.LastName
FROM
  Person.Address a
  INNER JOIN person.Person AS p
    ON p.rowguid = a.rowguid
WHERE
  City           = 'SEATTLE'
  AND PostalCode = 98104
OPTION (QUERYTRACEON 4199, 4137);

-- B
SELECT
  a.AddressID
, a.AddressLine1
, a.AddressLine2
, a.City
, a.StateProvinceID
, a.PostalCode
, p.FirstName
, p.LastName
FROM
  Person.Address a
  INNER JOIN person.Person AS p
    ON p.rowguid = a.rowguid
WHERE
  City           = 'SEATTLE'
  AND PostalCode = 98104
OPTION (QUERYTRACEON 4199, QUERYTRACEON 4137);

-- C
SELECT
  a.AddressID
, a.AddressLine1
, a.AddressLine2
, a.City
, a.StateProvinceID
, a.PostalCode
, p.FirstName
, p.LastName
FROM
  Person.Address a
  INNER JOIN person.Person AS p
    ON p.rowguid = a.rowguid
WHERE
  City           = 'SEATTLE'
  AND PostalCode = 98104
OPTION (QUERYTRACEON 4199), (QUERYTRACEON 4137);
