[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") 
'''

[USER (data scientist)]: Great, now I want to create histograms for each of the mentioned variables. Given the resolution, I would also appreciate a response to my question: The average age of the credit customers is approximately how many years, with a standard deviation of about how many years? 

A. 35.5, 11.4,  
B. 37.7, 11.4,  
C. 35.5, 12.8,
D. 37.7, 12.8
E. None of above
