The alternatives provided really don't cover the range of possibilities too well.
2D is such a huge underbid that it should not even be on the list! Surely, if you think it is right to bid your diamond suit naturally, 3D is far superior.
So, I chose Dbl. But I don't really like Dbl much since partner has, for all practical purposes (if partner has some reasonable values), denied the presence of a 5 card major. It sure doesn't require much to overcall 1H or 1S unless your partnership practices a very stodgy, super sound overcall structure!
But, as I mentioned, other bids occur to me. One is the aforementioned 3D. The other is 3C - if partner will understand this to mean that I have a solid 7 card suit - is 3C. I would not trot 3C out at the table undiscussed, so for me, 3D seems best.
3C showing the solid 7-card suit and an outside A is fine if you play it that way; I would say "standard expert" is preemptive (3H over 1H and 3S over 1S are the seven-carder). The biggest problem with 3C is that you're going to go set in 3NT on hands that may make 6 of a suit (partner will bid 3NT with xxx KQJx xx J9xx, where 3NT may go set and 6H is likely cold).
3D is fine, too, but it takes up a lot of bidding room (you might have a slam in any of four denominations).
Also, both of these bids give up on playing 1cX. Partner could have xxx xxx void AQT9xxx, you know.
Your comment about partner denying a 5-card major is not correct. Partner could have a 7-card major for all you know:
xx Kxxxxxx x xxx
Partner isn't going to bid anything with this hand, but you can likely make 7H.
I think X, 3C (if agreed that it's this hand), and 3D are reasonable; each has its pluses and minuses.
