Correct answer: B
Answer: 1:1
Step 1: Choose an easy total number of invited guests, for example 100.
Step 2: Calculate invited by gender: 60% of 100 = 60 males; 40% of 100 = 40 females.
Step 3: All invited females attended, so female attendees = 40. Total attendees = 80% of 100 = 80, so male attendees = 80 - 40 = 40.
Step 4: Ratio of males to females among attendees = 40:40 = 1:1.
Therefore the correct ratio is 1:1.
