Your job is to determine by searching and reading further information of which term you can answer the question. Indicate your choice as 'a', 'b', 'c', or 'd'. If you think more than one option is plausible, choose the more probable option to help you answer the question.

Question: How old was the king when he conferred a title on Viscount Netterville? Passage:Viscount Netterville was a title in the Peerage of Ireland. It was created in 1622 for Nicholas Netterville, 1st Viscount Netterville (1581–1654), son of John Netterville of Dowth, County Meath. He was a favorite of King James I of England who in 1622 conferred the title on him "in consideration of his many good qualities". He suffered considerable financial hardship during the English Civil War when the English Parliament, after the failure of the Royalist cause, sequestered his estates, along with those of his eldest son, John, the 2nd Viscount. During the Irish Rebellion of 1641 John, who was adhered to Roman Catholicism, was accused of favouring the rebels, and it does not seem that either side to the conflict fully trusted him. Possibly for this reason his son Nicholas, the 3rd Viscount, had some difficulty after the Restoration of Charles II in recovering the family estates. Because of Nicholas's loyalty to James II the estates were again forfeited after the Glorious Revolution of 1688, but were later restored to his son John, the 4th Viscount.
