The electronic configuration of boron is 1s^{2}2s^{2}2p^{1} , which means that it has a partially filled 2p subshell. This is because boron has only one valence electron, which occupies the 2p subshell. Hence option B is the correct answer.

Option (A) is incorrect because the 2p subshell of boron is not completely filled. Hence option A is incorrect.

Option (C) is incorrect because the 2s subshell of boron is not completely filled. Hence option C  is incorrect.

Option (D) is incorrect because the 2s subshell of boron is completely filled.. Hence option D is incorrect.
