Cross tab query or PIVOT?

In the SQL Selects below the first one will get you an example of my data

The select unions is what I need as output

The Question Types can be literally anything and may be from 3 to 5 types
(IndividualTypeID is tied to an origin so everyone within that origin will have the same origin)

Not all Individuals will have all the Question Types
But they will all be constrained within a "set"
In this case... my example below... 2.
Marital Status and age


DECLARE @table TABLE
(
    IndividualID VARCHAR(100),
    QuestionType VARCHAR(100),
    AnswerText VARCHAR(100)
);
INSERT INTO @table
(
    IndividualID,
    QuestionType,
    AnswerText
)
VALUES
(4819540, 'MaritalStatus', 'Single'),
(4819540, 'Age', '25-75'),
(4819546, 'Age', '18-24'),
(4819599, 'MaritalStatus', 'Married');

SELECT * FROM @table



SELECT 4819540 IndividualID, 'Single' MaritalStatus, '25-75' Age
UNION ALL
SELECT 4819546, '', '18-24'
UNION ALL
SELECT 4819599, 'Married', ''
