You've been provided with a dictionary named people_d that holds data in the format: 'name': (age, height). Create a function named people_information that accepts two parameters:

• d (intended to be a dictionary).
• name (intended to be a key within the dictionary).

This function should display the following details (based on the data format in people_d):

Name: <the key from the dictionary, or the `name` parameter>
Age: <the first item of the tuple associated with the key `name`>
Height: <the second item of the tuple associated with the key `name`>

For example, given the name 'Alex', the output should read:

Name: Alex
Age: 23 y.o.
Height: 178 cm
