Hello, can you help me figure out the answer between B and D? Thanks.

1)Yule Tube, an engineer at The Mixing Co., produces a video for use in a briefing to top management that depicts Yule mixing and making his newly invented composition.Management is sold on the new composition and wants to seek patent protection.However, before the patent application is filed, a copy of Yule's video ends up on YouTube.Mixing's attorney checks the YouTube site and learns that Yule's video had been recently posted and has had no views to date.In the U.S., the new composition:

a)is no longer eligible for patent protection because Yule's disclosure is an enabling disclosure to a person of ordinary skill.

b)is no longer eligible for patent protection because even though the video has not been viewed, it is available for viewing and, therefore, is considered published.

c)might be eligible for patent protection if the new composition is not available in nature.

d)is still eligible for patent protection because Yule is the inventor and the public disclosure did not take place before Yule invented the composition.

is still eligible for patent protection because Yule, as the inventor, can never bar his own invention from patent protection, regardless of when the video was posted and even if he was not the person who posted the video.
