Confused about the "30 days before" part of wash sale rules

This question is specified for situation where I can sell shares by lot.
For example I own a stock XYZ and the transaction goes like this.

* **Day One:** Buy 100 shares at $20 (Lot A)
* **Day Eleven:** Buy 50 shares $15 (Lot B)
* **Day Forty:** Sell 100 shares at $10(at a loss)

If my broker(Fidelity) allow me to choose which lot to sell, and i choose 50 shares from my Lot B and 50 shares from Lot A. Does this triggers wash sale?
