The symbol of helium is B. He.
Explanation:
Chemical Symbols: Each chemical element has a unique one- or two-letter symbol. The first letter is always capitalized, and if there is a second letter, it is lowercase.
Helium: Helium is a chemical element with the atomic number 2. Its symbol is derived from the Greek word "helios," which means "sun," because it was first discovered in the spectrum of sunlight.
Other Options:
A. H: This symbol represents hydrogen, not helium.
C. Hl: This is not a valid symbol for any element.
D. Hm: This is also not a valid symbol for any element.
Therefore, the correct answer is B. He.
