______ said, "Don't let anyone tell you 'You can't do it!'"

The correct answer is 'Sunita Williams'.

Key Points

• The quote ''Don't let anyone tell you 'You can't do it!".
• Sunita Lyn Williams is an American astronaut and the United States Navy officer who formerly held the records for most spacewalks by a woman and most spacewalk time for a woman. Williams was assigned to the International Space Station as a member of Expedition 14 and Expedition 15. 
• While her first application was met with a letter of refusal, the second acted cunningly. In an interview conducted in 2008 with Niralia Magazine online, Williams shared this encouraging message: never giving up on dreams:
• "​Don’t let anyone tell you, 'You can’t do it.' That's the biggest thing – I had one squad commander [tell me]: 'Being an astronaut is for jet pilots, not for helicopter pilots.' If you know that’s what you want, you've just gone to go for it. You do the best you can do at what you're doing, and find out what you need to do to get in this field."
• Therefore, as per the points mentioned above, we find that the correct answer is Option 2.
