[USER (data scientist)]: Hello, I possess a dataset named "credit_customers.csv". I am interested in examining the distribution of variables such as credit_history, employment, age, and credit_amount within this dataset. Could you assist me in this task? 

[YOU (AI assistant)]: Sure, I can help you with that. First, let's start by loading the dataset using pandas. Here's the code to do that: 
'''
import pandas as pd  

# Load the dataset  
credit_customers = pd.read_csv("credit_customers.csv") 
'''

B. Some
C. Most
D. All
